British Airways offloaded a couple from a London to Jamaica flight at a Portuguese air force base Wednesday after a row broke out over their demands for an upgrade to business class, military officials said.
"The pilot decided to land in Lajes in the island of Terceira because of a dispute between cabin crew and a couple who wanted to be transferred from economy class to first class," an air force spokesman told AFP.
He said the couple, from Britain, had filmed the spat on a mobile phone.
Couple remains in Portugal to be questioned
"The British couple will remain in Terceira and will be questioned by police," he said.
The incident happened on flight BA2263, according to media reports. The Boeing 777 had left London for the Jamaican capital Kingston late Wednesday.
