Two identical names on one PNR
Hello, I am about to buy LAX-LAS tickets with Spirit for a group of six in total, but the problem is that two people have identical name. Neither of them have any middle name so there is really no way how to differentiate (both of them are adults; nobody use jr./sr. in their passport). The airline website will not allow me to proceed with this and ask me to fix the problem.
I know I can divide the group in lets say 3 people in 2 PNRs but I would like to avoid that and have just one PNR for multiple reasons. Is there a way how to do it?
