I thought this was worthy of a post. My dad, who is already a Million Miler with United (and also Delta), started digging through his old frequent flier cards a few weeks ago, scrounging for a Continental card, so he could possibly merge his lifetime Continental miles with United as of the first of the year. Anyhow, we found his old Eastern / Continental Airlines card. What a relic! It was on a flimsy piece of paper, rather than on the plastic that “modern” frequent flier cards are on.
