Travel by water often provided more comfort and speed than land-travel, at least until the advent of a network of railways in the 19th century. Travel for the purpose of tourism is reported to have started around this time when people began to travel for fun as travel was no longer a hard and challenging task. This was capitalised on by people like Thomas Cook selling tourism packages where trains and hotels were booked together.[10] Airships and airplanes took over much of the role of long-distance surface travel in the 20th century, notably after the second World War where there was a surplus of both aircraft and pilots.[7] 

Travel dates back to antiquity where wealthy Greeks and Romans would travel for leisure to their summer homes and villas in cities such as Pompeii and Baiae.[7] While early travel tended to be slower, more dangerous, and more dominated by trade and migration, cultural and technological advances over many years have tended to mean that travel has become easier and more accessible.[8] Mankind has come a long way in transportation since Christopher Columbus sailed to the new world from Spain in 1492, an expedition which took over 10 weeks to arrive at the final destination; to the 21st century where aircraft allow travel from Spain to the United States overnight.
In theory, all the systems show the same data; in practice, however, they get a little out of sync with each other. If you're looking for seats on a sold-out flight, an airline's home system is most likely to have that last, elusive seat. If you're looking for the lowest fare to somewhere, check all four systems because a fare that's marked as sold out on one system often mysteriously reappears on another system. Some airlines have rules about flight segments that are not supposed to be sold together even though they're all available, and at least once I got a cheap US Airways ticket on Expedia, which didn't know about all the US Airways rules even though I couldn't get it on their own site or Travelocity which did know about them. On the other hand, many airlines have available some special deals that are only on their own Web sites and maybe a few of the online agencies. Confused? You should be. We are.

Four giant airline computer systems in the United States handle nearly all the airline reservations in the country. (They're known as CRSs, for computer reservations systems, or more often now GDS for global distribution systems.) Although each airline has a ``home'' CRS, the systems are all interlinked so that you can, with few exceptions, buy tickets for any airline from any CRS. The dominant systems in the U.S. are Sabre (home to American and US Airways), Galileo (home to United), Worldspan (home to Delta, Northwest), and Amadeus (many European lines.) The company that owned Galileo and Orbitz recently bought Worldspan, so the two GDS will presumably be merged. Many of the low-price start-up airlines don't participate in any of these systems but have their own Web sites where you can check flights and buy tickets. Southwest, the largest and oldest of the low-price airlines, doesn't participate, either. Southwest's web site gets car and hotel info from Galileo, but the info seems not to flow the other way. Orbitz one of the big three online travel agencies, runs its own system which is "direct connect" linked directly to many of the airlines.
Wait times are assessed automatically as follows: on departure, the passenger’s boarding pass is scanned when he/she enters the queue, then again just before he/she begins the individual screening process and, on arrival, when the passenger lines up in the visitors or residents queue in the primary inspection area and again when he/she exits from the area behind the customs officers’ posts.

The confusion is even worse if you want to fly internationally. Official fares to most countries are set via a treaty organization called the IATA, so most computer systems list only IATA fares for international flights. It's easy to find entirely legal ``consolidator'' tickets sold for considerably less than the official price, however, so an online or offline agent is extremely useful for getting the best price. The airlines also can have some impressive online offers on their web sites.

Sexual assault occurs frequently, particularly near hotels, in hotel rooms, in casinos, on cruise ships and on the beach. Avoid excessive consumption of alcohol, do not consume any drugs and don’t accept rides from strangers or from unlicensed taxi drivers. Due to incidents of sexual assault, it is recommended to be wary when embarking on jet-ski rides with licensed or unlicensed operators.
