Yes, this part has me confused... When we've traveled between Europe and the DR with Condor, anything needed has been clearly listed on the airline website, hence we have traveled without any surprises, without any issues...I completely understand, you could see them filling in paperwork on the film. I still have no sympathy, they must have realised that paperwork was required and should have known what paperwork it was. I am presuming it was the passenger locator forms for Belgium, not the Dominican e-ticket.
Other thing, so filling out forms made them so late that check-in closed? How much earlier did they arrive vs. the check-in closing time?
