Maximise your Avios, air miles and hotel points

Get £100 off a £500 United Airlines flight when you pay with American Express

Links on Head for Points may pay us an affiliate commission. A list of partners is here.

If you are planning a trip to the United States, there is an interesting new cashback offer available via American Express.

You will receive £100 cashback when you spend £500+ on a United Airlines flight before 9th December.  You must book via united.com and the offer is restricted to the first 20,000 people to register.

If you are targeted, the deal shows under the ‘Offers’ section of your online statement.  I doubt it is available on your British Airways American Express card, however!

Thanks to Saif for this.
