Sitting in the AA lounge at EZE now, I can confirm that the lounge is small (hard to find a seat!),
Yes it's not the biggest of lounges but neither are any of the other ones I have been in.....I guess lounge space at EZE is kind of restricted.
It was very quiet when I was in it for the BA LHR flight but very busy for the QF SYD flight. I can imagine it must be bursting at the seams in the evening for the AA flights.
Food is nothing to write home about but that was to be expected although there are still plenty of nibbles to keep hunger at bay.....and the booze is decent.
