I held top status on our preferred carriers, CO and Dl for 3 straight years in a row a few years ago. The DL flights were almost all to Europe and San Juan (all through ATL) and CO for the domestic trips. I was managing a group of engineers doing plant start-ups and always on call. Although my company had a policy of u/g to business class for trips 5+ hours, we managers were encouraged to “set an good example” and book only coach. Looking back it was a very grueling time.
