I just want to say how good it is that OP is staying on top of both PNRs. At least he/she didn't buy this trip for the whole family on April 1, get a schedule change on April 6, then show up for original departure on June 1 after the new flight departed and freak out since he/she never checked the itinerary since April 1 or try online checkin. It's amazingly helpful to look at itineraries periodically.
