Upgrades on Cubana are possible ..by PAYING $250 dollars at the check-in in Havana.Cash only no credit cards. I am also in the business and was told that this was the only way.When we arrived in Havana in September for the return flight to LGW I was determined to upgrade as sitting on a broken seat for over ten hours (like the outbound leg)was not an enticing prospect.There was a hurricane in progress and all the lines were down so there was no access to ATM's and as we "ONLY" had $300 the staff at the desk were "unable" to help.On boarding we noticed cash changing hands between the CC and "cuban" pax who were then whisked forward to ..actually can't recall what it was called ...but the "club" section. At least the seat weren't broke ...but it was darned uncomfortable!!Bring something to entertain yourself as the inflight was grim.....Having said all that though I LOVED HAVANA!! But NOT Cubana ....
