Last season Easyjet where using the ex-GB Airways fleet, the same as used previously when BA ran the route.
I did hear rumours that Easyjet were going to reconfigure the seating i.e.:move them closer together to get more seats in,I don't know if they have done so yet.
They are pretty much the same as other operators aside from the fact that they don't allocate seating in advance.
As with other airlines the cost of food and drink is silly,on the way back the guy next to me must have spent all his spare cash on 3 miniature beers at £4 each! As they were less than a half pint each this must be almost the most expensive way to buy beer on the planet. As I remember it a small bottle of water was something like £2
I was frankly not that desperate for a beer, call me a cheapskate if you like!
