Today I had to get UA's web support to ticket an award booking on ET (LAX-ADD-CPT). The agent only keyed in my middle initial, not my full middle name.
I also have GE. My KTN is attached to the PNR.
I am not so much concerned if I don't get pre-check at LAX, but I do want to be comfortable I will not have an issue at my connection at ADD.
Would appreciate any input.
