It's obvious that you need to start bringing a few subwoofers on your trips so you can make better use of airport time *and* collect listening experience in a wider variety of room sizes.
Some of the larger terminals might be good for 4pi response measurements too. Much better than going up a tower in the middle of winter
>>Would two EP350 V3 sound better than one EP500 v2?
I have very little experience with this kind of comparison, just going from theory, but IMO it's going to depend quite a bit on room and seating position. A single EP500 would probably be the way to go if your room is "good", but if your room is "difficult" (in any of a variety of ways) then you have options with two subs which you don't have with one. As an example, if you want good bass over a fairly large listening area then two subs (by virtue of being placed in different positions) can often help.
Can you tell us a bit about your room ?
