Hopefully, you have a record of your itinerary with flight numbers and dates. A little bit of appreciation in the form of a letter goes a long way. LOTS of people write to COMPLAIN, but not as many bother to note exceptional service when it happens. With the dates/numbers, NWA will be able to find out who the crew was and pass your appreciation along. Believe me, this kind of thing really brightens everyone's day. It has been a demoralizing time for the airline industry and you will be a welcome ray of sunshine.
