The Aero Club is exactly what it says - a flying club for members, which allows non members to stay.
The advantages are a competitive price, a lovely bar and restaurant area with excellent food at reasonable prices, no need to go into the city centre, and most of all a wonderful ambience with a club feel and loads of historic photos and artefacts.
The disadvantages are pretty ordinary rooms though with all basic necessities, some traffic noise from the main road just outside the perimeter fence, and no online booking.
It is also vital for first time visitors to realise that the Aero Club is not at THE airport (JKIA) but at the older Wilson airport about 20 mins away by taxi.
I'd go back again just to soak up the atmosphere in the clubhouse.
