Yesterday I flew from FLL to MSY via HOU. The connection at HOU was tight and I had to get from gate 4 to gate 48. When I got to the gate the B group had started boarding. I got on and began looking for 2 seats together. I asked about a few seats that were apparently being saved. I moved on. I found two together (an aisle and a middle). I put my jacket on the middle and waited for my wife who showed up a few minutes later. While boarding continued I watched as several people asked about the availability of a number of seats. Every passenger simply moved on. Everyone was polite and no one seemed to mind.
