Called ... got booked in B (M wasn't available on this route) and was able to use 25,000 miles to upgrade ... a pretty good bargain as paying for the one way would have been over twice the price! $20 per ticket charge was well worth the money to get this over and done!!

Now that we're booked in BE ... have questions:

We'll have about 4 hours between flights to enjoy the lounge. Looks like this flight has been leaving from terminal E. What's the best BE lounge at ATL?

Also, booked seats 3D & 4D (wanted both window seats) on the 767-400ER. Is this side better than the A side, i.e. less traffic? Thought since it was away from the boarding door it might be quieter. We have over 10 months until we fly so I can make changes as necessary.

Thanks!
