easyBoy, sorry that I wasn't as clear as possible. EasyJet have added an additional set of emergency exits on their Airbus 319 aircraft which allows them to seat more than 148 passengers. I remember reading that with just the standard two over wing exits the 319 can only seat a maximum of either 143 or 149 pax, I forget the exact total.
easy has also, in order to get as many as possible onboard, 156 seats I'm told, the rear of the cabin only has what seems to be a galley-ette, or a half-galley on one side of the aircraft.
bmi have no such ammendments, so in all-economy, we could only get 142, or possibly at a stretch 148 in our A319s.
