I just booked with XL. I had a discount code that allowed me £15 off per person - saving £30. When I got to the second page of the booking I found the "standard" baggage allowance has been reduced to only 15kg. You can buy an "extra" 5kg for £7.50 per person per flight. So that is the £30 back on again. That is downright sneaky.
But I am not going to let anything upset me today.
