What are the baggage costs for an easyjet flight?
They don’t say the cost on their website to do it this way, other than to say the cost is dearer than doing it on-line. This is usually about £6.00 each way on-line depending on the airports involved. At the airport you must pay at the Airport sales desk. A better alternative might be to register with easyjet as a “member”. Quite simple, with loads of benefits, no cost and you should be able to pre-book your luggage, just as if you had done it at the time of booking. To do this just click on to “My easyjet.com” on the Carriers regulations page on the link below. Good luck.
