After 10 years of business travel, this is how I cope at the airport:

• You’ll get there, even if you’re late.
• Don’t worry about lines, just wait in them.
• Few people know what they’re doing here, don’t let their stress stress you out.
• There are no special snowflakes, unless you have a doctor’s note.
• The word of airline staff is law, you can’t argue against the agent of the FAA.
• Relax and walk slow.
• If you want a better experience, pay more or pay your dues.

When in doubt, and even if it contradicts the above, you can always:

• Move fast and get out of the way.
