Avios points, which are part of the British Airways Executive Club loyalty program, typically have an expiration date if there is no account activity for a specific period. Generally, Avios points will expire after 36 months of inactivity in your Executive Club account. This means that if you do not earn or redeem Avios points within this timeframe, your points may be removed from your account. However, any activity, such as flying with British Airways, using a partner airline, or even making purchases with your Avios, can reset this clock and extend the validity of your points. It is always advisable to keep an eye on your account activity and to regularly check your balance.
