I am glad to hear it's a glitch as I somehow assumed this was a carriers' liability issue. Airlines need to know that a traveller will be admitted on arrival, otherwise they (the carrier) are obliged to return that person at their expense in the event they are bounced by immigration. Sometimes, a person who is not a citizen of their final destination, and does not have a return or onward ticket, needs to be checked for their suitability for boarding. It happens to me quite a lot as I travel to Brazil as a final or return leg yet hold a British passport (but have permanent residence permit that is outside the knowledge of BA). I always assumed BA were worried I would be bounced and hence would have to be flown back to London at BA's cost.
