Award flights on British Airways are calculated based on distance; the further you travel the more points (avios) will it cost to redeem a flight. The calculator includes British Airways destinations as well as its oneworld partner destinations.

If the itinerary includes a connection, the award rate for each segment is calculated individually. Rates are then summed up for the total miles cost.

Domestic UK connecting flights are included in the rates from London to the destination abroad.
The taxes, fees and charges always need to be paid with money.

Up to seven people can combine their points and thus increase their possiblities of booking an award flight. Members of the British Airways program (Executive Club) have had this option for a while.

Study on Miles Redemption
Generally speaking value-oriented airlines have much better award seat availability than the full-fare carriers. In a study done by Switchfly, frequent flyer programs like topbonus (air berlin, NIKI) and Rapid Rewards (Southwest Airlines) showed excellent seat availability for frequent flyer program members.

The study also looked at trends and indicates that member rewards are getting better across the board. Two full fare programs that were singled out for their improved seat availability were Executive Club (British Airways) and United Mileage Plus.
