I don't want to appear as an Easyjet apologist, but to see fair play I have to make a small point about the admin fee.
Shed says that it should be shown up front as it's part of the fare. Sounds reasonable at first glance, but that assumes you're only booking the one flight.
Even as a single traveller (which I tend to be most of the time), you may well book several flights in the same transaction; for instance, if you're travelling somewhere on a weekly basis you might book a block of flights to take advantage of the current cheaper price (and get the job out of the way for a while).
For that booking the admin fee is a total of £9, even if there are (say) nine journeys involved; so it would be wrong to advertise each flight as including a £9 fee. In this example the fee is only £1 per flight.
