Fares south of the border have remained pretty high, so any sale is welcome. Frontier is having a sale from various US cities to Cabo, Guadalajara, Ixtapa, Mazatlan, and Puerto Vallarta with fares beginning at $198 RT plus tax to all cities except Puerto Vallarta which is $258 RT plus tax, which usually runs a bit over $100.

Purchase by June 21 midnight for travel July 9 to October 16. Lowest fares are Monday-Thursday on some routes, and on others Frontier only flies once or twice a week.
