Separate J and F sections don't make much sense to me... In PRG and MLE the contract lounges have reserved seating areas for EK F but this makes sense as seating is in shorter supply.

The only tangible difference between the J and F lounges in DXB is the food offering which is unlikely to be extended to outstations (contrary opinions welcome). I guess the extended Spa options are of interest to some, but again that will not be brought to GLA.

The beverage selection in the F lounge does need to be differentiated from J.
