Over on his travel blog, Christopher Elliott writes that if you want to ensure you’ll get the reward program miles you deserve, you should hold on to your boarding pass. In his example, a frequent flyer with Air France couldn’t get his Delta miles credited even though the airlines codeshare, because Air France demanded the original Delta boarding pass, which the customer had thrown away. Elliot managed to get the airline to cave on this instance, but he points out that it’s easier (and better in case of an IRS audit) to hold on to them “just in case.”
