Overweight and oversized baggage: 

Overweight bags: 
• British Airlines will charge 65 GBP / 75 EUR / 100 USD / 100 CAD per overweight bag and one-way journey. If you’re flying from a country that uses a different local currency, the GBP amount will be converted to the local currency. In some destinations, additional local taxes may also apply. 
• Several airports such as London Heathrow, London Gatwick, and various locations in North America, accept payment through credit or debit cards only. Cash is not accepted, and Avios cannot be used as a form of payment.
• British Airways’ 23kg baggage weight limit applies to each bag and can’t be split between multiple bags. Bags over 32kg won’t be accepted as checked baggage.
• If your itinerary includes a flight operated by another airline, their baggage policies may vary. Be sure to verify the details before your flight.

Oversized bags: 
• There is a maximum dimension of 190 x 75 x 65cm for oversized bags. 
• Bags that exceed the standard size but fall within the maximum allowable dimensions are considered out-of-gauge bags. These bags can be considered as part of your checked baggage allowance, but they need to be checked in at the out-of-gauge bag drop at least 90 minutes before your flight departure to ensure that they travel with you.

24-Hour Cancellation Window: If a customer cancels their booking within 24 hours or less from the time it was booked, they are eligible for a full refund without any penalties with the exception of bookings made for travel within 24 hours. 

Requested for a refund by calling any of their contact centers here.

The fare a passenger paid is for the specific flights, route and dates as shown on the e-ticket receipt.
Please be aware that the flights indicated on the e-ticket receipt cannot be used in a different order. This means that if a passenger fails to notify British Airways beforehand about any modifications required, and decide not to board a particular flight (also referred to as a “no show”), it will render all the remaining unused flights in their itinerary null and void, and they will be cancelled automatically.

If a passenger needs to change all or part of their journey and if their fare type allows it, British Airways can recalculate the new fare for their proposed change. (However, for customers who booked their ticket with a travel agency/online travel site they would need to refer back to them to make changes.)

Service 2
• Assistance to and from the aircraft; depending on the airport, will be by either electric buggy or airport wheelchair
• Help with stairs if the aircraft is parked away from the terminal building
Service 3
