Travel is the movement of humans between different remote geographical areas. Travel can either be one-way or round trip, done by feet, car, bike, train, plane, boat or other modes, and is one way or round-trip traveling. There are three main types of travel: land, sea or air. Most of the world’s population lives in a ‘land-bound’ culture, primarily on farms and in small villages across the countryside.

Land travel is travel that takes place on ‘land’ – in a vehicle, on a trail, or hiking along a nature trail. Getting tested while traveling on land often happens because of the increased risk of vehicle collisions, which involve striking a moving object (such as another vehicle or rock) or falling from a great height (which is more likely in mountainous regions). People who travel in vehicles for extended periods of time, such as business executives on business trips, tend to be in higher risk for getting involved in automobile accidents than other types of travelers. And those who travel by other means such as bicycles, motor bikes or rowing boats can also be at higher risk for injury. All forms of travel raise the risk of injury or death when traveling.

Air travel has fewer risks than travel on land, mainly because of air traffic control, which limits or prohibits most types of travel on certain days of the week. Airlines place flight restrictions and create more advanced and more expensive seating arrangements to combat the low turnout for flights during certain seasons, such as holiday weekends. Flight restrictions also create a greater likelihood of passengers to get sick or have other personal issues that may affect their travel. Some airlines also place some restrictions on the size of luggage that passengers can carry, creating even more severe problems for those who need special items with fragile valuables.

Water travel is very popular and allows travelers to travel to any destination in the world within a 14 days time span. Unfortunately, travelers must adhere to very strict rules and regulations for carrying electronic or portable devices on board such as personal digital assistants, cameras or laptops. These devices are banned from being carried in the cabin of the aircraft and must remain in a container located outside of the plane. If this device is not allowed, the traveler will be forced to make other plans or leave the trip early. This makes water traveling one of the most difficult types of travel.

The United States has experienced a rash of airline related terrorist attacks over the past several years, leaving the traveling public with heightened security and travel restrictions. As a result, more people find themselves traveling via air rather than by land for long distances. One of the largest changes in travel has come in the form of nonstop flying during the months of August and September. Many of these flights fly from major US airports and include many first class amenities and business class options that would normally be found on international flights.

When making plans for international travel or going on a cruise, it is important to remember that there are some restrictions in place for most international travel and air travel. Many airlines and cruise ships have restrictions on the number of passengers that can be safely placed in an aircraft, the number of bags that can be brought onboard and the amount of money that can be taken out and brought back onboard. Most cruises have a limit on the number of nonstop, non-stop trips and there are usually a few nights of blackout in major ports around the world as well. Always check with your travel advisory service or the cruise line to make sure you are complying with all of the local, federal and airport regulations.
