It'll take a day or two for things to become more clear.

The way I take things right now:

1) if your itinerary is messed up and you want changes, then it might make sense to call up sooner than later; or
2) if your itinerary is messed up and you don't want changes, sit pretty for a few days and then follow up; or
3) if itinerary is not messed up and you want changes, then it might make sense to call up sooner than later; or
4) if itinerary is not messed up and you don't want changes, then sit pretty for a few days and then follow-up.
