I woke them up this morning at 0545 to make sure they made the hotel shuttle to the airport at 0630. They should have had plenty of time to make their flight but because their cell phones are dead, I'm unable to confirm it. I'm now tracking the flight but as of now (0900) it isn't showing that it has taken off.
Update at 0906: I just checked the Delta website and it shows that it took off at 0832 and is expected to arrive 15 minutes early at 1011. Time to go to the airport. Don't want to be late.
Update at 1114: Picked them up and got them home. Both of them glad to be home. Alis says she's not going to leave the house for three days. It is good to finally have them home. Now we just got one more to get home.
