If traveling for leisure, travel agents offer airline included packages. These packages offer accommodations, air travel and often activities. Discounts are given when full packages are purchased. One downside to these packages is that the air travel may not be convenient for you even though it may be more affordable. Multiple stops and layovers can be common during these flights.
Another way to compare for price and convenience is to contact the airlines themselves. Calling or going to a certain airline's website can yield discounts while also allowing you to know of flights times, layovers and other flight information. This may be time consuming.
Internet travel search engines capture the attention of travelers looking for affordable air travel. These websites go by the preference of your travel dates, times and the number of stops the traveler would not mind making. After all the information is entered, these website search all airlines with openings on those dates, times, etc. Often advertising special deals, some of these websites also have hidden travel fees that you will want to look out for.
