You may have seen the recent news that Delta Airlines has been aggressively trying to stop canceling flights. And it worked.
Delta also used some slight of hand to reduce complaints about wait times for baggage retrival:
When late-night arriving passengers at Salt Lake City(SLC) complained about the wait for baggage, Delta responded by directing nighttime arrivals to the furthest gate. Baggage processing time stayed the same, but passengers spent more time walking and less time twiddling their thumbs at the conveyor, and complaints nearly disappeared.
SLC isn't the only airport to try the technique—this NYTimes piece from 2012 tells of the same tactic being used in Houston.
That explains a lot! Several years ago, we landed at London Heathrow after a long, long flight. This was very early morning, and on a large full plane, so lots of tired passengers and loads of luggage. We came through from the furthest gate, and had to walk what seemed like miles. We were so pleased when we got to baggage reclaim that the carousel was already full of our plane's luggage. Now I realise it was probably just a crafty ploy!
UA at IAH doesn't have this problem with luggage. It matters not that your airplane parks at E18 which is the farthest gate from Terminal C baggage claim which is where baggage claim is for all domestic UA flights that arrive in Terminal C, D or E....making a brisk walk of 10-15 minutes or the above ground train that will take you five minutes....you will still have 30 minutes to wait for your luggage.
Now that is some customer service, yet I applaud DL for making an attempt to compete with UA on this issue!!
