If you’re like me, you probably spend a great deal of time looking for cheap flights using Google Flights. However, if you’ve ever tried to book flights, especially those departing outside of the United States, you have probably come across is often the least expensive option when booking a flight found on Google Flights.

After years of seeing listed in the results below my desired flight, I finally booked a flight through the travel agency.

My experience was seamless but it was not without its quirks and hurdles. It’s pretty clear that makes its money not through flight bookings but through additional paid services offered by the online travel agency. It turns out that these services are, for the most part, completely useless. Here’s what it was like booking flights with

Here’s what you should know before booking a flight on

What Is

Most travelers have probably heard of sites like Expedia, Orbitz, and CheapOair. These three sites are popular online travel agencies or OTAs. An OTA is a private third-party company that sells seats on flights, rooms at hotels, or allows customers to book rental cars. Customers are booking the same flight, hotel, or rental car as those booked directly through an airline, hotel, or rental agency. In many instances, travelers save money when booking through an OTA.

It is worth noting that travelers who book with OTAs usually don’t save much at all. There are instances in which travelers snag an amazing deal through an OTA, but this is a rare occurrence.

With the bulk of travel reservations being handled online, there is an almost endless list of online travel agencies. One of these newer OTAs is

This enables users to see all of the flights available for their given search as well as most of the available fares for a flight.

However, is somewhat unique in that the website provides virtual interline itineraries. This means that will allow customers to book an itinerary that includes flights operated by multiple different airlines. According to, the company wants to go so far as to become a “virtual global supercarrier.”

An interline agreement is an agreement between two or more airlines. These agreements allow an airline to sell seats on another airline’s flight as a part of a single itinerary. For example, American Airlines and JetBlue have an interline agreement allowing the two airlines to sell seats on each other’s flights on select routes.

What is unique about is that the OTA allows travelers to book interline itineraries with airlines that do not already have an interline agreement. This might sound like an ingenious business model. However, as you will see later in this post,’s virtual interline agreement itineraries are not all that passenger-friendly and could cost travelers hundreds in unexpected travel costs.

Aside from the ability to book complex itineraries with flights operated by numerous different airlines, offers little more than existing websites like Expedia or Orbitz. So, why book with over one of these other sites?

How Is Cheaper?

The reason is able to offer flights at a lower price than most other sites is thanks to its somewhat questionable ticketing practices. As previously mentioned, will let customers book complex itineraries with flights operated by numerous airlines that do not already have existing interline ticketing agreements. Additionally, the OTA attempts to force customers to rely on their customer service team for all itinerary changes, cancellations, and refunds.

More popular OTAs like Expedia and Orbitz allow travelers who book using their platforms the flexibility to manage their itinerary with the assistance of the airline on which they booked. Typically, the only thing an airline cannot do for travelers who booked through an OTA is issue refunds.

Instead, the travel agency that a passenger uses must issue refunds or handle canceled itineraries. Aside from canceled itineraries and refunds, passengers are almost always able to go through an airline to manage their third-party booking.

Excessive Upselling on is an exception.’s booking process makes it appear as though travelers can only manage their itinerary through the customer service team. As a matter of fact, the OTA goes so far as to upsell its customers on the ability to contact its customer service team. It is important to remember that, aside from refunds, airlines have the ability to manage a passenger’s itinerary even if they book through a third party.

The only instance in which it would make sense to utilize’s customer service team is in the event that a passenger books one of the platform’s “virtual interline agreement” itineraries. According to, these itineraries can be managed like most other interline itineraries if a customer has purchased the ability to access the platform’s customer service team.

Still, upsells its customers on all itineraries. Even the most basic itineraries require customers to decline multiple customer service add-ons.

Selling Services It Can’t Guarantee also sells additional services and amenities. This is similar to an airline upselling passengers on seats and in-flight services. What is important to understand about a third-party OTA upselling customers is that there is no way to guarantee that an airline will honor any of these services or amenities.

If you have ever booked a flight using American Express’ booking platform, you likely encountered the following message when selecting seats. “Seat Requests are passed to the airline, but cannot be guaranteed. Check with the airline soon after booking to confirm.”

American Express makes it abundantly clear to its customers that seat requests are sent over to an airline but there is a chance they will not be honored. This is because American Express is simply requesting those seats for the passenger.

Deep in’s terms and conditions, the OTA notes that services and seats are not guaranteed. Most passengers likely overlook this as it is not made clear during the booking process. It is also quite odd for an OTA to push any services that are not checked bags and seats. Nevertheless, does just that.

Even after a customer pays to access’s customer service, there are more fees to make changes to itineraries. Fees are incurred when changes are made to a itinerary even if the airline has a no-change fee policy.’s aggressive upselling is likely one of the main reasons the OTA can offer flights at such a low price. OTAs like also earn a commission from the airline each time a flight is booked. But a cheap flight is a cheap flight. If someone is willing to forgo the ability to make changes to their itinerary or forgo access to customer service in return for a cheaper flight, why not book through

Should You Book a Flight on

In most cases, I always bypass the savings offered by online travel agencies in return for the peace of mind I receive when I book directly through an airline. Airlines also place restrictions on benefits and the ability to earn points or miles when a traveler books through a third party.

However, there are some instances in which the savings are worth the risk. The question as to whether or not you should book a flight on depends on the specific flight or itinerary.

The main question you will need to ask is “How much are the savings worth to me?” How much of a risk are you willing to take? Do the fees associated with booking with a third party outweigh the savings?

How Much Are The Savings Worth To You?

I recently made the decision to forgo booking directly with the airline and instead booked a flight on I made this decision based on how much I valued the money I would save by not booking directly with the airline. In this case, VivaAerobus, the airline operating the flight, was selling a ticket on the airline for around $70 USD. was offering the same flight at around $46 USD. I decided the $30ish in savings was worth it.

If I had been traveling a few days later, the same flight when booking through VivaAerobus is currently available for just $19 USD. Meanwhile, that flight is available for $16 USD on In this case, I would have booked directly with VivaAerobus as the $3 USD savings are just not worth the risk that comes with booking through an OTA.

How Much of a Risk Are You Willing to Take?

In the case of the flight I had booked through, there was already a significant amount of risk associated with this itinerary. The flight departs on the first day that the departure airport opens its doors to the public. There is a relatively high chance that this flight will be canceled should the airport delay its opening date. Getting to the airport for this flight is also going to be somewhat of a challenge as I am taking multiple airlines and connecting through multiple airports.

Since the risk was already quite high, the risk associated with booking through was insignificant. Something like a delay in a connecting flight will most likely make this itinerary impossible.

Do The Fees Outweigh The Savings?

Since this was my first time booking a flight on, I took a risk and decided to decline all additional fees. This came with the possibility of incurring an itinerary modification fee for something as simple as selecting a seat. In the end, the risk paid off.

Once my flight was ticketed with VivaAerobus, I was able to select a seat using the airline’s website. I also had the option to select additional services including priority boarding and an increased baggage allowance using the VivaAerobus website. All of these add-ons offered through the VivaAerobus website were quite inexpensive.

In this case, since I did not incur any fees when booking on, the fees associated with the savings offered by the OTA were definitely worth it.

This upcoming trip was the perfect opportunity to allow me to try out booking a flight on With my flight now ticketed and additional services paid for using VivaAerobus’ website, I am pleasantly surprised by my experience with At the time, however, the constant offers for additional services including customer service (something already offered by VivaAerobus) was a major red flag.

The Bottom Line

There is an inherent risk when booking with any third-party booking platform. After having booked a flight on, it is apparent that not all online travel agencies are the same. Though the platform often features the least expensive fares and even allows customers to book extremely complex itineraries, there are notable cons to this OTA. actively works to get customers to book add-ons and services that are entirely unnecessary. If you are able to navigate around the platform’s nickel-and-diming, you may be able to snag a great deal on your next flight. It comes down to how much a traveler values the savings and how much risk a traveler is willing to take. If all of the pieces fall into place, may be a good option when booking your next trip.
