You're not jumpseating so you have no reason to "check in" with the crew. You bought a ticket, sit in the seat. If what you're looking for is a possible upgrade into first class, you could do a couple things:

1. If you have bennies on whoever your flying on, list you and your new wife for 1st class. If there's seats available, sit in them and refund your ticket.

2. Assuming you probably bought your ticket off Orbitz like everyone else and can't refund your ticket, talk to the gate agent. Tell her you're an employee and if there's any way she can bump you up it would be appreciated. Make sure you actually talk to them and feel them out. If it's a bad day, you're probably hosed.

3. Wear your ID when you get on the airplane. Say hi the FA, strike up some convo, tell him/her that you're going on your honeymoon and bought a ticket. Don't ask about 1st class...if they have common sense (and most mainline FA's have been there awhile) they'll bump you up if they can.

Don't bother the crew with this kind of thing. They don't know, nor do they care. All it's going to do is get in the way of the boarding process and make you look cheap. Maybe you'll get up front, maybe you won't. Since I'm a commuter, I'd be excited just about having a guaranteed seat on a plane.

Well, sorta guaranteed...you never know these days.
