Earlier today while sitting in a horribly crowded and overheated gate area at CPH and watching the clock tick away on our connection I DM'd the @United account with my PNR and asked to be protected on the later flight. I sent the message at 7:10am EDT. I got a reply back at 7:29am EDT noting that the additional segment had been added to my record and a follow-up email noting some potential weather delays on the UA side which might help my chances. Not only did they look at what I asked and respond quickly and professionally, but they went the extra step to try to allay my concerns. I could get used to that sort of service. Compared to the @united of old this is a HUGE step in the right direction.
