The easiest way to get the most complete info is to just put "One Great Team" in the search function after logging into Deltanet .

Beware. There is definitely an art to using these things. There must be a (T) fare available between the cities you are flying between. The agents dont like to have to hunt for these fares, but some are nice....otherwise see below.

The easiest way to check this is by going on Delta.com and selecting "Book a Flight". The available fares change every day so all because it's not bookable one day does not mean it will be the next. Also you might have to try different airports. I know the small airport near where I live that has no Low Cost Carriers never has any of these (T) fares. So in order to use these passes I will be driving 2 hours to an airport that also happens to be served by AirTran. I think the fact that there is more competition make Delta offer (T) fares in that particular market.

Once you have the flights you can call ( I think its just the 1-800-My-Delta, there will be a prompt specifically for these passes once you dig yourself deep enough into the system) and book.

It really is kind of a pain, but I'm happy to have them traveling to a pretty popular destination this summer. Good Luck!
