Frontier Airlines pushes direct-booking with $100 overhead bin fee if you book elsewhere

Frontier Airlines plans to start charging up to $100 for a carry-on bag and $2 for coffee or soda, although its announcement on Wednesday did say that passengers will get to keep the whole can. The new carry-on fee is for bags in the overhead bin, so small bags under the seat will still be free. Frontier said it will charge $25 if the fee is paid in advance, $100 if travelers wait to pay until they're at the gate. Frontier spokeswoman Kate O'Malley said the $100 fee is to get travelers to take care of the charge in advance. "We don't want to charge that," she said. Airlines began charging for the first and second checked bags in 2008. Passengers trying to avoid those fees have been stuffing as much as they can into carry-on baggage stashed in overhead bins, meaning those bins often run out of space. Fees are one way to get passengers to bring less on board
