Don't stand in line. Call you Airline Flight Reservations on your cell. The reservation agent is as capable as the agent at the desk you'll see at the airport. The agent on the phone maybe able to get you on another flight on another airline carrier. They all use the same computer system.
Be kind, patient, polite but assertive. You're the customer. They need your business, but not your attitude. It's no ones fault. It part of flying.
Always carry your medication, contacts supply's and a clean pair of underwear. I've lost my suitcase once for 24 hours.
