Can I take a free upgrade to first class when my wife didn't get one?
Do you think that would be ok with her?
I'm a nice guy and I deserve it. Life is not always fair.
Your wife probably feels the same way that you do, and she will wonder why she never gets these little breaks in life. If you can't take your wife with you into first class, then for her sake, you should decline the upgrade, otherwise you will just make her jealous.
Fuck she's not more special than anyone else. Besides it's her own fault for not paying attention.
This is a tough social conundrum and the only proper solution is to offer it to your wife or ask her for your permission to accept the first class seat. I suggest demonstrating your selflessness and take the high road on this one. Your wife will think much more highly of you afterwards.
