Travelling as PAX between MAN & DUB with Aer Lingus (I always book a window seat in advance) what the crews do is they tell PAX in front of Row 14 to use Front Steps & PAX behind Row 14 to use Back Steps for boarding at the gate - I once got an aisle (assigned) seat...never again, because people who had been assigned window seats were stepping over me and it was horrible on a full flight...it makes more sense to allow window seat PAX to board first and doors as above - the new terminals at DUB have hardly any airbridges and only the evening flights from DUB have them at the older gates - as for arriving at MAN its like a building site with that silly little overcrowded bus, which on evening arrivals there is only one for a full flight, 2 if you are lucky
