We all know how expensive it can be to fly with your bike. We update the airplane bike fees on our Web site for the National Bike Summit every March, and the rates are inconsistent and pricey. Luckily for those of you who fly Frontier, there is good news!
Frontier has removed the flat fee for checked bicycles and will now include them in the standard baggage allowance, meaning customers traveling on Classic or Classic Plus fares can include their bike as one of their two complimentary checked bags and Economy passengers would pay $20 if the bike is one of their first two checked bags. Bikes will be exempt from any oversize fees, but subject to overweight fees and excess bag fees, if applicable. This is similar to the carrier’s current policy for golf clubs and skis. Frontier recommends to give yourself an extra 30 minutes for check-in if you are checking your bike — a small price to pay for free or exceptionally low bike check-ins!
