Are There Budget Airlines at SBP?
A common question from travelers is whether budget carriers serve San Luis Obispo. Currently, Southwest Airlines, Frontier, and Spirit do not fly to San Luis Obispo (SBP).
Travelers loyal to Southwest often fly into Santa Barbara (SBA) or San Jose (SJC) and drive the remaining distance. However, “budget” travel is still possible from SBP by booking early on major carriers.

Tips for Booking and Travel
When flying from a regional airport, a few strategies can help ensure a smooth journey:
- Book in Advance: Regional flights have fewer seats than jumbo jets. Prices can spike closer to the departure date.
- Check Connections: When flying American, connecting through Phoenix often avoids the weather delays sometimes found in San Francisco or Chicago.
- Arrive Early for Parking: While security lines are short (TSA PreCheck is available), parking lots can fill up during holidays.

Pets and Baggage Policies
Traveling with pets requires adherence to specific airline policies. All three carriers at SBP allow small pets in the cabin for a fee, provided they fit in an approved carrier under the seat.
- United & American: Generally restrict specific breeds in cargo; cabin pets require advance reservations.
- Alaska: Known for being particularly pet-friendly, but space is limited to a certain number of pets per flight.
Regarding baggage, standard policies apply. Most economy tickets on these major carriers do not include a free checked bag unless you hold the airline’s credit card or elite status. Always weigh your bags before arriving at the airport to avoid overweight fees.
