The boarding was good but the line for check-in is pushed off to the side because of the recent construction. It’s fine but cramped as people jostle to get checked in. Also, we weren’t able to use our online check in and printed boarding pass so we had to basically check in twice.

Make sure you have plenty of time between flights if you are delayed.

If you don't have checked luggage, no need to be in a rush to line up. There will be a spot for your little carry-on rollie bag, so relax until the line is down to board the plane.

Bring a sack lunch -- airport food was very expensive.
