Leaving Tomorrow! Quick DME question...

[Lollipop's Mom]

If we are at the airport and our flight gets switched/cancelled and we end up coming in on a different flight, do we have to try and call DME to let them know?
It would be a pain to be trying to make another flight, knowing I have to make a phone call somehow to alert DME.
My thinking is 'no' we don't have to let them know, but I just want to be sure.

Nope. As long as you have the reservation, you're set. The arrival flight is to help DME plan...

Now the departure flight, if the flight number changes, that's when it really matters. When you check in at the airport after arriving, they'll confirm everything there.
