HORRIBLE. Didn't send my airline reservation # or flight ticket. The link for which the CheckMyTrip email stated I could obtain the airline reservation # just have an error message. So I'll be showing up at the airport with no reservation # or proof from the airline that I actually should be given a ticket. Guess I may now end up buying a more expensive (because of purchase date) ticket at the airport from the airline (or WORSE if the flight is full). HORRIBLE!!
