General
The answer to this question will vary based on the airline you are flying, potential membership and status of any associated frequent flyer program, and other random factors such as the disposition of the person checking you in, or the fare basis of your ticket. The dimensions of a bicycle transport bag are normally larger than conventional* luggage, which classifies it as “special” baggage or equipment. For detailed information about traveling with your bicycle box or bag, please check with your airline carrier (have your bag dimensions handy) and familiarize yourself with their luggage policy.
*The standard size and weight of a conventional suitcase or bag are no larger than 62 dimensional inches (the sum of the length, width, and height) and under 50 pounds in weight.
Airlines will generally waive any special baggage fees for your bicycle travel case if it meets standard size and weight restrictions. However, this is unfortunately not always true. It may also depend upon the person checking you in and their perception of your bag and its dimensions.
Bicycles are generally accepted on a space-available-basis and there may be a limit as to how many you may check-in. It is a good idea to book a spot for your bicycle when purchasing the ticket. Costs for checking in a bag last minute at the airport may be more expensive as well. For detailed information about traveling with your bicycle box or bag, please check with your airline carrier (have your bag dimensions handy) and familiarize yourself with their luggage policy. Here are the common weight and size limits:
- Maximum weight: 32kg (70lb)
- Maximum linear dimensions (length + width + height): 292cm (115 in)
Removing a bicycles handlebars, and often the pedals too, is a standard requirement indicated in most airline carriers baggage policy terms and conditions.
No. There is absolutely zero risk of this happening. The included airbags are high-volume, which means that they cannot reach high pressure. (The same goes for bicycle tires) The inflatable air protective bladders for your wheels and bicycles inside the Biknd bicycle travel cases can easily withstand pressure changes during flight.
