Hello all, and thanks so much for this newbie forum.

I was about to let 20,000 AA miles expire when I ran into this forum and others subsequently.... My husband and I love traveling and have flown 5 times this year for leisure, but I would always book based on the cheapest ticket out there, regardless or airline or miles.

I am in shock of all of the potential benefits and rewards that we have been missing out on!

I signed up for the Citi card offering 100,000 bonus miles promotion to get started.

I am overwhelmed by all of the abbreviations and lingo. What does YQ mean?

If I search for flights on AA.com, will codeshare flights automatically show up, or do I have to call and ask?

What should I do with the 100,000 miles??? My husband didn't want the CC, so I'd have the share them with him (or pay his way).

Would it be worth it to save the miles until we reach elite status using full-cost fares, then use the miles for the lowest redemption possible and upgrade using the elite status?

Sorry for the several questions covering a broad range of topics... but I'm as newbie as they come, so thanks for your time!
