During British Airways' first quarter conference call this afternoon, chief executive Willie Walsh said: "We are looking at opportunities in the future to raise revenue through very limited unbundling of our product."
While stressing that BA will retain a clear focus on being a premium airline, Walsh said there may be some changes to its "current customer proposition".
When asked for an example, he said this could include changes to non-premium customers' baggage allowances although silver and gold card holders would be exempted from the move.
"We would still offer a bag free of change, but looking at excess baggage charges, there may be some revenue opportunities for us there," he said.
BA recently revealed that it is scrapping all meals, except breakfast, on its short-haul flights.
