Need some advice.
I currently have DPS - HKG - TLV booked in biz class.
The problem is that 2 of the tix from DPS to HKG are currently in econ since there were no more biz class that day. My &$%$-up is that I booked my 2 young kids in the those seats. I was told to not worry by the AA agent, that s/t can be done at the gate, but ppl on FT weren't so certain. But I was told that CX will often open up more availability closer to the date, although I don't want to rely on this.
So I just checked again, and see that I can fly DPS - KUL - HKG - TLV in biz class for all 4 of us. I'm concerned about the problems booking LY. If I try to switch this itin, will I be at risk of being left w/ nothing? Also, will they charge me a fee for anything?
