I wrote Northwest airlines telling them about my great flights with them last weekend on Wednesday at 12Noon.At about 12:05PM I got an email from NW saying they had received my comments and would try to get back to me within 2 days.
I checked my email at 3PM and there was already a letter saying how they were going to pass my comments to the flight attendants!
It wasn't just a form letter either because the responder even took the time to wish me a great trip to Hawaii this summer(when I hadn't even mentioned that in the letter!!!!)
Also, I thought it was neat that a supervisor of customer service was responding to my letter, and so quickly.
Now that's what I call Customer Service!
