Fare structure & what's included
As a low-cost carrier, Frontier Airlines typically advertises a stripped-down base fare. Cabin bag in the overhead bin, checked bags, seat selection, priority boarding, and on-board food are usually charged separately. The total ‘door-to-door’ cost can still be lower than a legacy economy ticket if you travel light, but it pays to price the bundle, not the headline. Always pay for bags online; airport prices are dramatically higher.
Hubs & main bases
The airline's primary operational bases include the airports listed below. Bookings that originate from a hub almost always have more frequency, more competitive pricing, and better recovery options if a flight is cancelled. If you are connecting through a hub, allow at least the airline's published minimum connection time plus 30 minutes during winter or in known-bad-weather seasons.
Booking & check-in tips
- Book directly on the airline website. Third-party agencies often charge service fees and complicate any future change request.
- Check in online the moment check-in opens (most carriers open 24–48 hours before departure). Late check-ins are first to be denied boarding when a flight is oversold.
- Pre-pay any bags or seat selection at booking, not at the airport. Gate fees are punitive.
- Sign up for the loyalty programme even for a single trip. Many carriers waive change fees or offer faster rebooking for members.
