Thanks for the input. There are some great suggestions here.

I do agree that if I do get upgraded and she gets mad that is pretty silly on her part...remember its just a seat..

I like the idea of switching seats with her during flight of course if it is ok with the FA.

I am not sure why she would get mad, maybe jealous..not sure..I asked her and cant get a very good answer besides it would be inconsiderate.

Thanks again.
