When going on a vacation, purchasing airplane tickets is a very major factor. For budget travelers, this means planning the vacation ahead of time, so that they can still have time to look out for discount deals on airplane ticket prices. And for some, they don't have an idea where to start.

There are several tips on how to land the perfect airplane ticket and when you should actually start looking. Believe it or not, there are certain days in a week where you can always find discount prices on your selected airplane flights, which, compared to the normal fares some airlines offer to the public, always makes an astounding difference.

For example, did you know that the weekends are the best days to look for discounted airplane fares? This is based on the study conducted by Expedia and Airlines Reporting Corporation. On their latest study on 2015, it showed that weekends provide cheaper rates than most days of the week. Before this report came to light, it was disclosed that Tuesday is the best time to look for airplane fares.

Why weekends? It's because several airlines have factored in the fact that most leisure travelers often buy their tickets during weekends, while those who travel for business often buy on weekdays. That's when they raise the price of their tickets.

Another tip is to subscribe on your favorite airlines' email alerts. This way, you'll instantly know if they're giving a surprise or last-minute promo deals, since these kinds of fares often get snapped up quickly. This is opposed to visiting their website every now and then, hoping for a price decrease.

Last tip is to not book tickets during Fridays. This is when airlines usually run out of cheap flights, hence the price hike. Just be patient and wait until the following day, Saturday, because that's when ticket prices go down.
