Prices are per one way.
Prices for connecting journeys are calculated as follows:
to/from or beyond Europe (e.g. Madrid to Boston via London) – you pay the price for just one of the flights; where the charges vary, you pay for baggage of the most significant sector which is usually the longest flight (e.g. for Madrid to Boston via London, you would pay the charge for the London to Boston flight only)
Prices are in UK pounds, US or Canadian dollars, and Euros. If you are leaving from a country that uses a different local currency, the UK pounds amount will be converted to the local currency.
Online purchase is not available on a few routes due to local airport systems but you will be able to pay for extra bags at the airport. At many airports, including London Heathrow, Gatwick and North America, you can only pay using a credit or debit card. Please check with a member of our staff at the airport to find out if options are available for converting cash to a prepaid debit card.
If you use a prepaid debit card, do not throw it away until your travel is complete, even if the card is empty. If we need to refund any costs, we will be returning these to your original form of payment.
If payment by cash is still available at the airport, it may incur a commission charge.
From 1 February 2019 Brazil prices are the same as all routes.
For connecting journeys through US/CA/MX and LGW the pricing applied to the first baggage will be the "All Other Flights" pricing.
