I dont think the airbridges in Pier C look too bad. I know the ones at Gates 28-32 look a mess on the outside but they are very nice on the inside. Gates 22-26 is the other way round. Gates 12B & 21 are probably the best airbridges at MAN but i think 21 is only used by Jet2 737-300's? Never seen anything else there?
now for A/C at gates 2, 4, 6, 8 & 10 which all (except 2) have airbridges??
Gate 4 does not have an airbridge either, i used it when i went to GIB in October and we had to go outside. In fact i think it would be good if Gates 9, 11 and 12A had airbridges too as it would save people getting wet!!!
