The terminal wouldn't cope with another 189 (assuming a FR 738) - there are only 3 gates. Not helped by everyone funnelled through 1 ADF payment point after checkin to then have 1 queue for 1 x-ray machine (there are 2 but I have only ever seen 1 operational) which spit you directly out into the duty free shop. The departures area would need some remodelling to say the least!
