I have, I hope, an easy question. I'm flying from BOS-DEN on US465 on Dec. 9th and I just used some miles to upgrade to First Class. I just got notice that my upgrade has been confirmed (I was waitlisted) and went to select my seats. I choose my seat (3A) and wondering if it's a good seat for an A320. Also, my original coach seat still appears as well as my 1st class seat, making it look like I have two seats on the flight...will this effect using Online check-in next week?
Thanks for your assistance! Long-time reader, 1st time poster!
