During the Holiday season (2003) we chose to eat at a rather expensive restaurant in Mauii. There were 4 of us and as I recall the bill was between $200 and $300. When it didn't post I called Idine. I was told that that restaurant did not participate with the airline I thought it would. I believe the airline was UAL.
I was told that each restaurant owner could choose which airlines to be involved with. Never made sense to me. Like a restaunteur knows enough about airlines to determine which to exclude? That seems pretty far fetched!
That lesson also reinforced the need to check each restaurant with the individual idine website. I think Idine really complicated the program when it made this move.
No wonder so many folks just don't want to be bothered with the program.
