will you earn silver on your segment to AUH or on the next segment ?
you may get access in AUH if u earn it on that segment but i dont think u will get in for LHR
the lounge in AUH is totally overcrowded
you can also buy a lounge day pass for one lounge in auh which is usually not too crowded if u have a long layover.. the food is not good as in EY lounge but u can find a place to sit down at least and have a couple of drinks
