In recent times smartphones have become extremely useful tools for travelers. We do less and less searches from the PC and make more use of mobile applications to find flights, accommodations, transportation schedules, etc. In this post, which will be the first in a series of articles on apps for travelers, we have selected some of the best apps for finding cheap flights. We welcome suggestions for expanding the list!

There are plenty of apps to search for flights, although few of them are 100% effective. At the time we already recommended our 5 favorite flight search engines and here you will see 3 of those search engines repeated because, in addition to being good in their web version, they have excellent apps. Our recommendation is that you try them all and then choose the ones that suit you best, but do not rely on a single card.

While you are traveling to Peru you may need to keep communication or a translation app. That’s why you may need to use one of our mobile phone plans for tourists to avoid high roaming costs. In order to make a nice trip here in PeruSIM, we will show you 8 apps to search for cheap flights.

1. SkyScanner

Skyscanner\’s mobile application is as good or better than its web version. No costs, no commissions, with low-cost airlines included, with alerts for price drops, numerous search filters, possibility of flying to anywhere, fare calendar, storage of recent searches, etc. In addition, you can create a user profile or log in so that your data, history, etc. are synchronized on the different devices where you use Skyscanner.

2. Momondo


Momondo is another of our favorite search engines and its app is also a marvel. Compared to the previous two, an interesting contribution is its ticket builder, which allows you to choose the round-trip flights separately in a very simple way. Like the Skyscanner app, it allows you to connect with your user and save search history, your preferences, etc.

3. Kayak

Kayak is another great flight search engine and has another great app. It brings almost all the features we have already discussed about SkyScanner, but it can also search for hotels and rental cars. And, as if that were not enough, it includes some utilities such as the tracker (to know if your flight is on time), basic information about airlines and airports, a travel manager and the explore tool, which allows you to see on a map the prices of flights to other cities from your home airport. The only negative thing about Skyscanner is that you cannot have a user profile.

4. OnTheFLy (ITA Matrix)

ITA Matrix is a classic for travel freaks in its web version. Its app, although simple and with little visual appeal, is also very practical. The most interesting thing about ITA Matrix are the advanced search options, which allow you to play with flexible dates and multi-destination itineraries. However, Ryanair and other low-cost airlines are missing in the results.

5. Hipmunk

Hipmunk, with its funny mascot and pleasant visual appearance, is another great app for finding cheap flights. It lacks nothing: multi-destination itineraries, user registration, numerous filters for results, search history, low-cost airlines included, simplicity, speed… For the moment the only thing that can be criticized is that it is not available in Spanish and that it does not allow to play with flexible dates.

6. Cheapflights


Cheapflights is also not translated into Spanish, but it is another very complete and visually pleasing app, so we could not ignore it in this compilation. As interesting details we would highlight the cheapest – quickest – smart value filter (which selects the cheapest flight, the fastest and the one with the best price/quickness ratio) and the visual price comparator, very useful if you have flexible dates and want to see which day it is more economical to travel.

7. Hopper

Hopper is a relatively new app with many features yet to be improved, but in the future it can be a good alternative or complement to the previous ones. The price search on a calendar with colors and flight tracking (with notifications on the mobile for lower prices) are very interesting, but for now what we miss the most is that the results show airlines as important as Ryanair.

8. Low-Cost flights and travel

Guía Low-Cost is a well-known Spanish website where offers and bargains on flights are published daily. These are not commercial offers, but rather notices of real bargains and mistake fares. In 2014, thanks to one of these fares published on Guía Low-Cost, we traveled with American Airlines on a direct flight Barcelona-New York for 150€ per person (final round-trip price). Their app is not exactly spectacular, but it is ideal to receive notifications of bargains and not miss these bargains.

Finally, we know that you have to keep communication with your relatives and friends, that you need to be able to orient yourself in new cities, that you might need help with translation and that you might need to search for restaurants or hotels. That’s why with PeruSIM you can buy a SIM card including the data plan of your need without having to worry about high roaming costs.
