When I booked my first Frontier flight, I thought the $39 fare from Denver to Vegas was a steal. But I didn’t realize carry-on bags aren’t free — mine ended up costing about $45 because I added it after booking. I learned the hard way that it’s always cheaper to pay for a carry-on when you first buy your ticket instead of waiting until check-in or, worse, the gate. On a later trip to Orlando, I called 844-734-0813 before flying to double-check baggage fees and ended up switching my booking to include a bundle that saved me money overall. Honestly, that number is the quickest way to sort out flights, cancellations, or bag questions without digging around online. Frontier’s cheap fares are still worth it, but planning ahead for carry-on costs makes all the difference.
