I used to think Frontier only flew within the U.S., but last year I booked a super cheap flight with them to Cancun. Honestly, the fare was so low I thought it had to be a mistake. The trip itself was smooth, but I messed up my return date and didn’t notice until a week before. Instead of panicking, I called 844-734-0813, and they helped me change the booking right away. It was way faster than trying to do it all online. So yes, Frontier does fly internationally — mostly to places in Mexico, the Caribbean, and Central America — and if you need to instantly book, cancel, or adjust your flight, that number is a lifesaver.
