If you’re a US citizen arriving at Chicago’s O’Hare airport on an international United flight I have just one piece of advice for you: renounce your US citizenship and stay overseas. Or maybe hop a freighter. O’Heck made London Heathrow look like a garden of earthly delights. My experience this week was a train wreck at every stage: bad information, rude and unhelpful staff, long lines, flight delays, inadequate waiting areas and buck passing on a governmental scale. Customs was fine, security was OK, but everything else was bad by any standard. Avoid O’Hare/United if possible.
