Until 11 March 2016, BA is offering passengers a free upgrade from Business Class (Club World) to First Class when they book a return flight.

Your outbound journey needs to be made no later than 9 April 2016, and your return by 16 April 2016. Crucially, you must book the flight with a travel agent or by contacting BA on 0844 493 0787. You will not be upgraded if you book online. 

There are limits to BA’s generosity. The upgrade will only apply to one leg of the flights, and only applies to bookings made in the semi-flexible R, D or C class, or a fully flexible J class. As such, you’re not going to be able to combine this offer with a bargain basement sale fare.

You can either upgrade on the outbound or return part of your journey – it’s up to you.

It’s well worth reading the terms and conditions in full before you make a booking, they are available at the foot of this page. In addition to those flagged above, key ones to note are:

• London Gatwick to Bermuda is excluded
• Flights must start and finish in the UK and Ireland
• The upgrade is subject to availability

Is BA First Class any good?
