This was the best! Everything moved quickly! This was a connecting flight for me and my child coming off an international flight that was delayed by a hour and we just zipped through that airport. We had to pick up our luggage, recheck our luggage, go through customs and make it to our gate within a hour to make our connecting flight and we got to our gate with 15 minutes to spare before boarding began. Everything just moved efficiently and before I knew it we were taking off. This was a two hour flight and drinks and snacks were offered. Just a great experience.
