A long flight in economy can drain you before you even land. The right seat upgrade can mean the difference between arriving refreshed and arriving exhausted. This guide shows you exactly how to upgrade your airline seat through Expedia, what each cabin class offers, how to navigate strict airline restrictions, and how to get the best value for your money.
Quick Answer
You can upgrade your seat on Expedia during initial booking checkout or post-booking in the “My Trips” portal. However, for many carriers—especially when upgrading post-booking or using frequent flyer miles—you should take your 6-character airline confirmation code (PNR) directly to the operating airline’s website or app. Note that Basic Economy fares generally cannot be upgraded.
Key Takeaways
- Expedia supports direct seat upgrades at checkout, but post-booking availability depends on airline system integration.
- Basic Economy and highly restrictive fares purchased on Expedia are strictly non-upgradable on almost all major airlines.
- To upgrade using airline frequent flyer miles or bidding systems, manage your reservation on the operating airline’s platform using your 6-character PNR code.
- Revisiting your itinerary 24 to 72 hours prior to departure often unlocks unsold premium cabin inventory at discounted prices.
At a Glance
| Time Required | 5–10 minutes |
| Difficulty | Easy |
| Tools Needed | Expedia account, Airline 6-character PNR code, valid credit/debit card |
| Cost Range | $100–$500 (Premium Economy), $500–$3,000+ (Business / First Class) |
Before You Begin
Before searching for a seat upgrade, make sure you have the following information readily available:
- Your Expedia account login credentials
- Your Expedia itinerary number and 6-character airline confirmation code (PNR)
- A target upgrade budget
- Your frequent flyer program member number
Having these details ready speeds up the process and prevents you from losing an available upgrade spot while searching for missing information.
How to Upgrade Your Airline Seat with Expedia: Step by Step
Expedia integrates seat selection and upgrade options directly into its booking flow. Follow these steps to find and secure the right option for your flight.
- Search and select your flight on Expedia. Navigate to Expedia’s website or mobile app and enter your departure, destination, and travel dates. As you proceed through flight selection, compare cabin tier options presented on screen.
- Review upgrade options at checkout. Expedia displays available Premium Economy, Business Class, and First Class seating options directly in the checkout portal. Review amenity differences and prices before finalizing your purchase.
- Access your booking in “My Trips.” If you have already booked, log into your Expedia account and open the “My Trips” dashboard to review post-booking seat selection options.
- Locate your 6-character Airline Confirmation Code (PNR). If Expedia does not display post-booking upgrade options for your carrier, find the 6-character airline record locator on your Expedia confirmation receipt.
- Check post-booking availability on the airline’s platform. Take your PNR to the operating airline’s official app or website. Airlines frequently offer direct cash upgrades, seat-selection maps, or mileage upgrade requests directly on their own platforms.
- Monitor inventory 24 to 72 hours before departure. Airlines release unsold premium cabin inventory closer to departure. Revisit your itinerary in the days leading up to your flight to capture late availability.
Pro Tip: Check your itinerary 48 to 72 hours before departure. Airlines often release unsold business and premium economy seats into upgrade inventory as they finalize cabin manifests.
Critical Restriction: Basic Economy Fares Cannot Be Upgraded
Before buying a flight on Expedia with the intention of upgrading later, pay close attention to your selected fare class. Major legacy carriers—including United Airlines, Delta Air Lines, and American Airlines—strictly restrict Basic Economy tickets.
Warning: Basic Economy fares purchased on third-party platforms like Expedia generally cannot be upgraded with cash, points, or frequent flyer miles under any circumstances. If you want the option to upgrade, always book at least a Main Cabin / Standard Economy ticket.
If you accidentally purchase a Basic Economy ticket on Expedia and realize you need extra space, take advantage of the standard 24-hour risk-free cancellation window to cancel the flight for a full refund and rebook into Standard Economy or Premium Economy.
Seat Upgrade Options Explained
Understanding what each cabin class offers helps you pick the right upgrade for your travel needs. The three primary upgrade classes are Premium Economy, Business Class, and First Class.
Premium Economy sits between standard economy and business class. Seats feature wider cushions, increased legroom, deeper recline, and upgraded meal service. It represents the most cost-effective upgrade and works well on mid-length flights where extra space is desired without a massive price jump.
Business Class is designed for long-haul comfort. Passengers receive wider seats that transform into fully lie-flat beds on international routes, priority check-in and boarding, higher baggage allowances, and access to airport lounges. Food and beverage services are significantly enhanced compared to economy cabins.
First Class offers the highest tier of luxury, privacy, and personalized service. Expect private suites, chef-curated dining, dedicated cabin crew, and premium lounge access. It commands the highest price point and delivers an uncompromised flight experience.
How to Choose the Right Seat Upgrade
| Factors to Consider | Importance |
|---|---|
| Cost of Upgrade | High |
| Seat Comfort & Lie-Flat Capability | High |
| Extra Legroom & Pitch | Medium |
| Seat Location in Cabin | Medium |
| Additional Amenities (Lounge, Meals) | Low |
Start by evaluating flight duration. For a short two-hour flight, premium economy or extra-legroom seats provide sufficient comfort. On an eight-to-twelve-hour overnight international flight, a lie-flat business class seat dramatically affects how you recover from jet lag upon landing.
Consider your personal comfort priorities. If you need to sleep soundly, prioritize lie-flat capability. If you need to work on a laptop, wider armrests and dedicated power outlets are essential. Always research the aircraft type flying your specific route, as seat configurations vary greatly across fleets.
How to Maximize Comfort in an Upgraded Seat
An upgraded ticket provides premium amenities—make sure to utilize them fully:
- Noise-Canceling Headphones: Business and First Class cabins frequently provide high-quality headsets connected to expansive inflight entertainment screens.
- Pre-Ordered Meal Service: Many major international airlines allow premium passengers to select their main dinner course online up to 24 hours prior to departure.
- Airport Lounge Access: If your upgraded ticket includes lounge access, arrive at the airport early to enjoy complimentary meals, quiet workstations, and private shower facilities.
What Seat Upgrades Actually Cost
Factors That Affect Upgrade Costs
Upgrade pricing depends on the carrier, route demand, time remaining before departure, and unsold cabin capacity. High-demand business routes during peak business days command high upgrade premiums, whereas mid-week leisure routes often present lower upgrade costs.
Typical Upgrade Price Ranges
- Premium Economy: $100 to $500 per segment, depending on flight distance.
- Business Class: $500 to $2,500+ for long-haul international flights.
- First Class: $1,000 to $4,000+ on flagship transcontinental or oceanic routes.
Warning: Always compare the stand-alone upgrade fee against the base price of purchasing the premium cabin ticket outright. In some promotional instances, buying a Business Class ticket directly on Expedia is cheaper than buying Economy and adding a post-booking upgrade.
Last-Minute Upgrade Deals & Bidding Systems
Many international carriers utilize automated upgrade bidding platforms (such as Plusgrade or SeatBoost). If your flight is eligible, you will receive an email invite or notification in the airline’s app allowing you to place a cash bid for unallocated premium seats 24 to 72 hours before takeoff.
How to Find the Best Expedia Upgrade Deals
Expedia occasionally offers promotional bundles and special fare combinations. Subscribing to Expedia price alerts keeps you informed about temporary fare drops on premium cabins.
When searching for flights, evaluate vacation packages that pair flights with hotel stays or rental cars. Airlines frequently release discounted premium cabin inventory when bundled inside a full vacation package on Expedia.
How the Expedia Seat Upgrade Booking Process Works
During the initial search on Expedia, compare the fare columns displayed on the search results page. Expedia outlines included amenities—such as seat pitch, free checked bags, and cancellation flexibility—side by side. Select the premium cabin tier before reaching payment to lock in the upgrade immediately.
Managing Your Upgrade Directly on the Airline’s Website
Because Expedia is an Online Travel Agency (OTA), some post-booking seat modifications must be completed directly with the airline.
- Locate your 6-character Airline Confirmation Code (PNR) on your Expedia itinerary receipt (note: this is distinct from your 13-digit Expedia itinerary number).
- Go to the operating airline’s official website or mobile app and select “Manage Booking” or “My Trips.”
- Enter your 6-character PNR code and passenger last name.
- Access the live interactive seat map to select preferred seating, purchase extra legroom, or buy a cash upgrade to Premium Economy or Business Class.
Managing Upgrades for Multiple Passengers
Upgrading a party traveling together requires careful coordination. If you are upgrading through Expedia or the airline’s seat map, make sure adjacent premium seats are available before confirming payment.
If only one passenger in your party receives an upgrade (for example, via frequent flyer status), speak with the gate agent upon arriving at the airport to ensure seating preferences and baggage allowances are handled properly.
Using Loyalty Programs & Miles to Upgrade for Less
While Expedia allows you to earn Expedia OneKey Cash on eligible bookings, you cannot directly spend airline frequent flyer miles inside Expedia’s checkout engine.
To upgrade an Expedia-booked flight using airline miles:
- Ensure you booked an upgrade-eligible fare class (avoid Basic Economy).
- Log into your airline frequent flyer account on the operating airline’s app or website.
- Retrieve your reservation using your 6-character PNR code.
- Select “Upgrade with Miles” or request a Mileage Upgrade Award.
Note: Be sure to input your airline frequent flyer number during checkout on Expedia so that you earn elite status credit and redeemable miles for your flight.
Tips for a Smooth Upgraded Flight
- Verify Seat Assignments Early: Re-check your seat numbers on the airline app 24 hours prior to departure to ensure equipment swaps have not altered your seating.
- Submit Special Dietary Requests: If your upgrade includes meal service, submit special dietary requests (vegan, kosher, gluten-free) at least 24 hours in advance on the airline portal.
- Arrive Early: Take full advantage of priority check-in lanes, fast-track security (where available), and premium lounge amenities.

Can I upgrade my airline seat through Expedia?
Yes. You can select premium seats and upgraded cabin classes during initial checkout on Expedia, or review upgrade options post-booking in the “My Trips” section. Alternatively, you can use your 6-character Expedia airline confirmation code (PNR) to upgrade directly on the operating airline’s website.
Can I upgrade a Basic Economy ticket purchased on Expedia?
Generally, no. Major carriers such as Delta, United, and American strictly prohibit seat upgrades on Basic Economy and highly restrictive fares. If you want upgrade flexibility, always purchase at least a Standard Main Cabin ticket.
How much does a seat upgrade cost through Expedia?
Upgrade costs vary based on flight distance, carrier, and demand. Premium economy upgrades typically range between $100 and $500 per segment, while business class upgrades generally cost $500 to $2,500+ on long-haul routes.
Can I use airline frequent flyer miles to upgrade an Expedia booking?

Upgrading during booking guarantees your preferred cabin and seating. Waiting until check-in or using last-minute bidding platforms can yield lower costs, but carries the risk that premium cabin seats sell out entirely.
