Today I created an acct with British Airways. They wanted me to convert to the executive club for free. This way I get Avios points. I googled Avios and saw Marriott was a partner. Is this the airline miles thing you can earn? I can't use these points or convert them to Marriott right?
I am making ONE flight - I made an acct and signed up simply for better protection on being walked AND in case there was any other advantages/promotions that came along.
So what is good about Avios and should I even bother for one flight? Do I get any rewards for just having a basic acct with British Air?
