Arriving after 11 is not a problem if you have booked DME ahead of time. Our flight arrives at 11:07 p.m. We are only going for a long weekend, so dh and I are going to each take a carry-on bag. That way, we won't have to wait for our luggage. On our return trip, we'll go ahead and check our bags. We received our DME tags the other day. All info. was correct.
