I Have used Easyjet for years to fly MTB to the alps - no trouble at all - just select / pay for bike on line booking system - just ensure you are under the max weight - 34 kg i think (please check) - so pack all you can up to that weight. i also recommend you pay for Easyjet Plus - as you can avoid a big queue at the airport trying to fight your way to the check in desk between the tapes that your bike bag is too big to fit between !
