Well I can survive without the F1-F4 gates though they were the most convenient to the Amex Club.

An overhaul and expansion of the E lounge (or a bigger space nearby) would be a huge improvement as the current location is always overcrowded, to the point that chairs are impossible to find.

I don't see how they can survive without the Rotunda if all the F gates (minus 1-4) are still in use. They will have to do some kind of temp club like they did at DEN. The E-clubs and G clubs will not simply not cut it as they are too small and too far. Personally I would not mind a grab and go if it is well stocked.

I am not a big fan of Terminal E but I guess we are stuck with it. Terminal D is quite nice with perhaps my favorite food vendors but a major hike from the UA counters - it will be fine if you don't have to check luggage.
