I’m not sure that there is any staff, you check in on the internet for “your” convenience, which takes much longer and is quite invasive, upload your drivers license, credit card again, then a facial recognition program after that, and for me, I always love a second and third check in as I usually book from an Expedia or such. I feel exceedingly uncomfortable with the amount of “verification” (for my safety) I feel safer speaking with an eastern Indian call center. If this is for my convenience, I’ll buy you dinner.
