Yes, you read correctly! You can buy certain flights from British Airways for under £10. Take a look at the screenshot above for a flight from Luxembourg to London in August for 10.79€, which is approximately £9.50. Of course, the flight out is more expensive making this a rather unique proposition. Nonetheless, it highlights that it is always worth investigating both the price of a return fare vs the price of two singles when booking flights with BA, as one may be cheaper than the other.
My advice, when booking British Airways short-haul, is also to book as far in advance as possible and ideally in European Business Class on Avios for free.
