Just looked at MMB for an upcoming JER-LGW-JER in early April- £220pp to upgrade to CE from ET... you must be joking! When we already have lounge access that seems ridiculous! That could be £220 more in Hollister... certainly know which I would choose!
BA upgraded me and my Dad to CE on our most recent JER-LGW, not the first time it has happened! It was nice though as it was the 7AM flight and we had a very good breakfast with bucks fizz. Nice way to start off a day!
