I'm not a fan of this airport (at least terminal 1).
For the security line, those not in first class or with TSA pre-check are routed 3 legs of a square rather than the direct route, for no real reason. (It would be just as easy to allow all travelers to go this way, and then split them into the two lines.)
Once through security, the terminal is carpeted throughout - which is difficult for rolling bags - and has fairly low, dark ceilings (compared to other airports).
They could also stand to remove some of the slot machines in favor of additional seating, since a majority of sections were full, with people standing around since no available seats.
Overall, just feels like an overly dated airport that could use a serious revamp.
