Frontier has announced new flights to/from Philadelphia, Washington D.C., Colorado Springs, San Jose, CA, and San Juan, with intro fares starting at $57 round-trip.
New service begins in April or May and each route will be operated on a limited basis. Check our fare details for specifics.
Intro fares must be purchased by 11:59 p.m. ET on February 5, 2018.
The Tulsa flights will start in San Jose, CA and continue on to Washington D.C. after stopping in Tulsa, which means there is also an excellent one-stop intro fare between California and D.C.
These fares all work in reverse as we well. Keep in mind that Frontier charges extra for any bags larger than a small personal item. Pack super light to get the lowest price. Checked bag fees start at $25 each way.
