In the past couple of decades a growing number of people have regularly used the airplane as their means of transportation when traveling internationally. When the preferred method of visiting overseas is one of the excellent jets available from most airline companies, it is important to understand that this increase in number of travelers makes it even more important to know some of the common rules and customs.

While most international travelers are quite comfortable with the requirements of moving by air from country to country, some get confused and disoriented even when they believe they are well prepared. But many travelers take far too little time to become familiar with guidelines and requirements set by airlines, airports and government agencies.

The first area of confusion might be the differences between domestic air travel and transatlantic air travel, for example. Many vacationers feel that, because they have flown in their own country many times they will be fine traveling to and within another country. While some domestic and international travel rules and customs are the same, there are significant differences.

The airport screening process for international travel is usually a bit more involved than for domestic travel, especially since 2001. This alone should be a sign to the traveler that more time should be allowed for getting to the airport, getting through the check-in and boarding process, and getting out of the airport. The importance of planning for enough time to connect with a following flight is just one item that should always be taken seriously.

Expect closer baggage inspection with international flights, for example. It does not matter that there are grandparents or young children in the group, the airport and Transportation Safety Administration will still inspect baggage and persons for illegal items.

In the early minutes of time at an airport, domestic and mingle, often using the same baggage check and passenger check-in facilities. Sometimes the two classes of passengers find themselves separated when the screening process begins, but in most airports this is not the case. Many of the larger hub airports screen all passengers and baggage with the same process and the separation into domestic and international flights comes only at the gate. Passengers will be asked to remove all jewelry, belts and other accessories that might set off the metal detector. This inspection process includes the shoes. Travelers should expect this and be prepared for it.

One of the common factors that hold up check-in and screening, with both domestic and international flights, is the lack of proper identification. Some travelers just do not seem to think ahead and when they are asked for picture identification, they have to dig through carry-on luggage or explain that they don't have it right at hand. Of course, these folks are usually asked to step aside, but the delay they created has already started. It is wise to have driver's license, passport and any other required identification accessible. Tip: Bring only what is required and leave other important documents at home. If there is doubt, ask!

These are just a few tips and guidelines that may smooth the way for international travel. Remember that there is never too much information when it comes to being prepared for traveling outside of the home country.
