5. Arrive at the Airport Early — or Earlier Still
We've all been told to arrive at least an hour before domestic flights. The operative words here are "at least." If your airport and traffic research indicates you need to factor in still more time, do it. The worst that can happen when you arrive earlier than needed is you'll spend more time hanging out at the gate, where you can grab a bite, do some reading or do a little shopping. At some airports, you can even get a spa treatment. All this is far less stressful than the worst that can happen when you arrive late.
6. Pack With the Wisdom of Experience
Know your airline's carry-on size limits and checked-bag weight restrictions, and pack accordingly to avoid delays at check-in or boarding. Before arriving at the airport, put ID tags both inside and outside of your bags. Some savvy travelers say using only carry-on luggage is the best way to travel these days: You'll not only save money, but also time at both check-in and arrival.
7. Prepare for Airport Security
On the day of your flight, put jewelry, watches, belts and change in your carry-on before leaving home. Wear only one jacket or coat, as opposed to multiple layers, all of which have to come off at security. Wear slip-on shoes or boots with zippers so you can get them off quickly. Head to security ASAP, with your clear, plastic 3-1-1 toiletries kit and your laptop or tablet computer at the ready to put into bins (remember that digital devices need their own bins) and your identification and boarding pass in hand. If we all were prepared at security, the lines would move faster — even at the busiest airports.
