The small Louis Tavern lounge is indeed a joke. I started to use the Oman Air Lounge (with Priority Pass) which is a quite nice alternative (when it's not crowded). It's next to the E gates from where EY is mostly departing.
Agree the Louis Tavern Lounge is a joke was there in Jan. I have recently booked two more flights from AMS-BKK Rtn in Business Class, sadly Etihad have lost my business to Qatar Airways gain. I have voted with my feet on this one, sorry Etihad but Jetihad one minute and Louis Tavern the next is enough to drive anyone away. I wonder what is on their agenda next?
