I need to book airport transfers before April 20th and wanted to know if anyone has tried booking the airport transfer if the primary card holder is not traveling. I checked with the customer care. They're saying that it's available only for primary card holder. However, in the app, when I'm trying to book, it's not asking for any ticket details for proof that I'm traveling. It's even asking the name of passenger and not automatically taking the primary card holder's name. Just wanted to know if any of you have tried booking for somebody else. TIA
