After a year of using my tags, only been noticed once, by a FA. Had a good conversation with them. Last month while taking the shuttle back to the car, noticed a FT tag on someones luggage, didn't get their FT handle, but had a short conversationn with them.
While being able to get on a eariler flight, with checked luggage, I am a firm believer that the only reason my luggage made it was because of the FT tag. Gate agaent got me on the plane (departing in 1/2 hour) and asked about any checked luggage. Told her it was a normal black roller, but had this really neat, bright yellow tag on it. She said that she would try to get it on. Low and behold, upon arrival, it was there. Saved my a trip back to the airport 6 hours later. All because of my FT tag.
