Good afternoon. I booked a flight for my Chinese wife to visit her daughter in Harbin, China this morning on you JustFly web service. Itinerar * ***-***-***. I picked a return flight that would allow my wife to accompany her daughter, son in law and baby on their visit to the US. The return flight from Harbin to Beijing is flight ****. I did notice that the connecting flight from Beijing to NYC was different. Our daughter's flight is Air China ***, my wife's is Air China ***. Irrationally I assumed the family would be on the same connecting flight from Beijing. When I compared the two Itinearies I caught the mistake and immediately called Justfly. I spoke to a lady, explained the situation and after about a half hour of my trying to explain the situation, she said she had the information and would send me an e-mail with the itinerary. I received the e-mail and nothing was changed. I don't think she understood me. I hope this is clear. I need my wife's connecting flight changed from *** to ***. My wife spoke to Air China and they told her that only your agency can make the change. I am an elderly gentleman with early onset dementia. When I woke up this morning my sugar was ***, after * hours without eating my sugar went up to ***...stress is killing me. Thank you for any help you can offer.
