The DH & I also always book aisle seats .... he's tall so he needs the aisle for some leg room, I'm just claustrophobic, so I like the ability to get up and stretch. I always hated in the old days (before on-line check in) that when we would check in at the counter, they would have change our seats to put us together giving me a middle seat - as if they were doing us a favor! These days I love on-line check in as, even after you've checked in, you can monitor the seats and if something better pops open, you can grab it. Last trip we got stuck over night in Tampa and had to take what we could get the next morning to get home. We'd already check in and had boarding passes - both in middle seats. Can't remember if the cut-off is 1 hour or 30 minutes, but I was checking the seating on my i-phone just before it cut-off when an aisle seat came open. Being nice, I gave it to the DH. All he had to do was ditch the paper boarding pass and use the i-phone app as his boarding pass.
Now if we could just get Southwest to fly to Cozumel, we wouldn't have to worry about all these baggage problems!! :depressed:
