There's nothing more aggravating than arriving at your destination groggy and red-eyed. Jet lag makes clear thinking difficult, leading to bad decisions at international business meetings, and recreational travelers find it detracts from the enjoyment of their hard-earned and time-limited vacations. Symptoms include fatigue and general tiredness, inability to sleep at night, loss of concentration, headaches, malaise and disorientation. It is caused by the disruption of biological rhythms as a result of rapid transitions across multiple time-zones. Such desynchronization of circadian rhythms also affects employees who transfer to night shifts.

The rules for when to arrive at the airport have changed a few times in the last couple of years, and even today the required time of arrival will depend a great deal on the airport you're using. Small local airports tend to be more flexible, and you can arrive fairly close to the time of take-off and still be able to board the plane. However, if the airport is fairly busy or if you're unsure of how early to arrive, please show up at least two hours before your flight to check your bags.
