If you bag is too big, regardless of the airline, then it needs to be checked in. Baggage rules are clearly stated. And FR still have the cardboard sizers which they patrol the queue with. EasyJet allow one bag. That is clear. You turn up with two, you're going to have to pay. And EJ is the only one who GUARANTEES that EVERYONE can bring a bag onboard, unlike FR who only allow first 90 or so. Sorry, but you have zero sympathy. Of you don't comply with the rules and get stung, of course you will prefer FR, for now.
