I booked a business class flight on British Airways using a combination of a companion voucher, 88,000 Avios points, and £399 in cash, plus an additional £220 paid for seat selection.
When I arrived at Heathrow Terminal 5, I was informed at check-in that my booking had been downgraded to premium economy because the aircraft had been changed to a Boeing 777 with insufficient business class seats. Several other passengers were also affected.
Despite raising concerns, there was no option to retain the original cabin class, and I was effectively rebooked into the lower cabin due to the aircraft swap. The downgrade also impacted my plans since I had intended to work during the flight.
The only compensation received so far has been a small refund of £24.50 per passenger, which feels inadequate given the use of points, voucher value, and paid extras. I am now planning to formally complain and seek clarification on what compensation is appropriate in this situation.
