Is that the same Globe Ground ticket desk that's opposite check-in desks 40-43 where HLX passngers check-in. Because that's where I asked and their reply was they I could not pay with cash but they passed me the phone and the number for HLX reservations. Of course I dont have a credit card so it was pointless. Anyway I contacted HLX to say it says you can pay cash at the airport. They replied that this was a mistake and they would take it off the website although it is still there.
