I was thinking of this on my trip home from New York. First, my wife had her jar of marmalade confiscated, because it contained more than three ounces. As she bought this at Eataly, she was displeased. She noticed she has her suitcase searched anytime we take off from La Guardia.
Then we noticed we were sitting on the bulkhead. The seat belts are different, you have to pay attention to the numbers on the buckle. Also, there is no seat to put your small bags under, therefore, you need to be able to store them in the overhead bin.
The lessons I learned flying on this trip:
1. You need to read the TSA rules in detail.
2. You need to know how the layout of a plane works.
3. It pays to walk with a cane, as you get to board first. Leaving the plane at your destination, you are on your own. Oh well.
