Considering the lack of available overhead space on most flights, along with those eager passengers who crowd the gate waiting to fill it, it's a wonder more carriers haven't started charging for carry-on baggage. You may recall Allegiant and Spirit were first to take the plunge a while back, but the trend soon fizzled. At least til today, when Frontier announced that they too will charge for carry-ons on some tickets starting in summer, with fees ranging from $25 to $100.

Only travelers booking Frontier's Basic fares via third party sites will be charged. All tickets purchased directly from FlyFrontier.com are excluded from the new fee. Charges apply only to carry-on luggage, and all passengers are allowed one free personal item, no larger than 18” x 14” x 8”, for under seat storage.

No exact date yet on when this new fee will kick in, but stay tuned!
