Frankly Id rather see AA put a small club in the C gates at LGA or work with TSA to create a C/D sterile area as it seems AA has more flights/seats daily going out of the C gates at LGA than TPA and my guess is LGA is a higher yield market. I find 50% of the time my gate is C and it doesnt make sense to go through the D security, go to the AC, back out of D and then through the C security.
If AA checks this board I would suggest that is a higher priority but Im sure either way they will have the numbers to figure it out.
