Overbooking is one thing; that's more than the max number of tickets being sold. However, with seat allocation it seems that a seta was allocated twice for the same flight. Surely this process was computerised. Howe is that possible? Or was there the dreaded human hand intervention? From the newspaper story, as published, it does suggest the rejected child passenger was not treated as sensibly as should have happened. He should have been 'kept under wraps' until an alternative flight was found. The airline screwed up it was their obligation to sort it out and take responsibility until it was. It would be slightly different for an adult.
What is ez's attitude to using cabin jump sets to solve problems? e.g. a broken seat that is deemed unusable at the last minute. Fly the pax, or off-load?
