The other day I was buying a flight down to London to see a client and used the British Airways website to book. I looked at various options to get the cheapest flight, but was a little surprised to see that the cost of flying from Glasgow to Gatwick costs more when you take less baggage.
Yes that's right, to fly with a suitcase up to 23kg in weight is £11 cheaper than just travelling with hand luggage.
Note: I know that BA's digital revenue management team can't be expected to get pricing exactly right and that errors will occur. However on this occasion I did book the cheap ticket and simply 'forgot' to take my large bag.
