I booked a rewards ticket for my mother-in-law to RGN, it is composed of ANA, Thai, and Eva flights. We were looking at the booking and noticed that the DOB was entered into UA's system as May 9th (5/9) instead of September 5th (9/5). A call to UA was able to fix it, and said everything was all set. I checked the booking on Thai and it is still showing up as September. The flight is in January, and I'd rather not go through and cancel and rebook if I can't get this sorted.

Any suggestions on what my next step should be?
