Get a 20% bonus on Starwood hotel transfers to American and US Airways

UPDATE – JUNE 2025:  This is an old article, and the credit card information given is likely to be out of date.

For some reasons we don’t know about, Starwood Preferred Guest was not included in the current 25% bonus for transferring your hotel loyalty scheme points into Avios.

American Airlines and its new sister company US Airways have stepped into the breach with an offer of their own.

Until 31st July, you will receive a 20% bonus on all transfers of SPG – and only SPG – points to American and US.

The home page for this offer is here for American and here for US Airways.

Usually, 20000 Starwood Preferred Guest points would get you 25000 American Airlines or US Airways miles.  For transfers initiated by 31st July, that is increased to 30000 miles.

Note that the terms and conditions say that the bonus miles may post up to 7 working days after the base miles.

This could be an attractive offer for some people.  Remember that AA does not charge fuel surcharges except on BA and Iberia redemptions – flights to the US on AA planes only incur Air Passenger Duty.  If flying to the Middle East, 30000 American Airlines miles is good enough for a one-way flight to Abu Dhabi in business class on partner Etihad.
