1. Poor signage. Trying to find gate A27 shouldn't resemble a treasure hunt!

2. Few or no places to recharge electronics. The reason goes without saying these days (especially since pay phones have all but vanished, and we need our cellphones to be charged at our end destination!).

3. Domestic terminal layouts which require passengers to leave the secured area to go from on concourse to another, or one terminal to another. (BOS, I'm looking at you!)

4. Limited meal options after clearing the security screening. Since we aren't fed on most flights anymore, and half of what we'd like to carry for snacking will get tossed out by the TSA as a prohibited "liquid," a decent array of dining options is important.
