On flights to or from the USA, it’s also possible you lost your preferred seat to a Federal Air Marshal; a “throne” seat would be preferable to a FAM because of the easy aisle access. If so, the airline is forbidden to disclose that reason; they would provide you with rubbish answers.
I though US Federal Air Marshals only operated on US flag operators. When the whole Air Marshal thing was started, Air Canada and the Canadian authorities needed to create a similar role in the RCMP to handle the Air Canada flights into Reagan National Airport. I believe it only applied to that one airport. Does Portugal even have the concept of an Air Marshal?
