(Remember that Hertz is not a British Airways Executive Club partner, so the only way of earning Avios with a Hertz rental is to credit it to an Iberia account. You can then move the Avios to BA or avios.com using ‘Combine My Avios’.)
Until December 20th you will earn TRIPLE Avios points on a rental of 3 days or more.
Paying standard rates, you earn at least 300 Avios per day – and up to 450 for a larger car. During this promotion, you will be earning 900 to 1,350 Avios points per day.
