Hubby and I took RCCL cruise in January, with a 4:30 flight home. We went to the airport right after disembarking and did curbside check in (we tipped $5, as we knew we were pretty early). We had our luggage unloaded within 5 minutes of arriving at airport. You would not believe how long the lines were inside to check luggage. My advice is to use curbside check in, we were so happy we did. Spent the day at the airport having lunch at Chilis, going to the bookstore, playing cards, shopping in the little stores, etc.. and actually enjoyed our day there, knowing that our luggage was safe and sound. Have Fun! Sue
