BA often discount their Club Europe Seats
British Airways frequently has sales, for Club Europe Seats. They often have great deals, with return flights starting at £200. I paid £200 to fly to Amsterdam in Club Europe and I paid £250 to fly to Copenhagen.
Even outside of sales, they often have good value fares. One great tool that BA have is their low fare finder. You can find the very lowest fares for many destinations at once. If you’re flexible, then you can get the lowest prices. It’s a great tool. More airlines should have it.
