for bmi short haul you do not have to list because we work on a first come first serve basis for other carriers. there is no special counter ( just shortest queue). res will let you know what the loads are like UK 0870 60 70 555. for the US flights ring res to list 1-800 788 0555 this will get you a meal. ORD -check in at T5 and in IAD check -in at UA counter.
Those in the star alliance we have a ZED fare agreement.
