I am kidding but these Boeings are a shame... with seats that cannot hold in the upright position: I remember Matthew, a friendly cabin crew, asking me whether my seat was already as upright as possible... Yes it was! but it would go down as soon as I'd rest my back on it...!
They should switch to Airbus :-)
I hate Easyjet but they aircrafts are much nicer... excepted for the horrible orange color everywhere in the cabin!
