Common mistakes when booking a flight and how to avoid them
16 March 2025Booking a flight may seem like a simple task, but sometimes it can take longer than expected, and certain mistakes can be costly. From hidden fees to itinerary mix-ups, there are many details to keep in mind to avoid unpleasant surprises. We want to help make your experience as smooth as possible, so here are the most common mistakes when booking a flight and how to avoid them.

Entering incorrect details
One common mistake is making an error in the name when booking, which results in a mismatch with the identification document you’ll use. Some airlines charge high fees to correct personal details, while others don’t allow changes at all, forcing you to make a new reservation. If less than 24 hours have passed since the transaction, call the customer service number of the agency or airline where you booked.
How to avoid it: Before confirming your purchase, double-check that the names match exactly with those on your passport or ID, especially when making a multiple or group booking.
Not checking airports and layovers
In cities with multiple airports, it’s easy to book a flight departing from a different airport than the one you arrive at. Additionally, some layovers can be too short, increasing the risk of missing your connection.

How to avoid it: In Trabber’s search results, we highlight in red when the departure or arrival airport for your outbound flight is different from the return flight.
Moreover, on the right side, where all filters are located, you can easily select only flights that use the same airports for both outbound and return trips by choosing the ‘Same airports for round trip’ option.
Not booking in advance
It’s a basic tip, but booking at the wrong time can make you pay more. Booking too late is usually more expensive, but doing so too early doesn’t always guarantee the best price either. And last-minute bookings should be avoided, as they are almost always costlier.
How to avoid it: Use tools like Trabber’s price alerts to receive emails or notifications on your mobile or browser to track how flight prices evolve.
Not reviewing fare conditions
Each fare has specific conditions regarding changes, cancellations, and baggage. Choosing the cheapest option without reading the fine print could mean paying more in case of changes.
How to avoid it: Before booking, check what the ticket includes: hand luggage, checked baggage, the possibility of changes or refunds, among others.
Not checking if baggage is included
More and more airlines, not just low-cost ones, are selling basic tickets that only include a small personal bag. If you need to bring a suitcase, you could end up paying much more than expected.
How to avoid it: On Trabber, you can see what baggage is included in each fare and its cost. Keep this in mind, as it can be a key factor for certain destinations. Additionally, we have created an updated list of baggage allowances for major airlines worldwide.
Not comparing prices properly
This may seem like an obvious recommendation, but many people book the first flight they find without checking whether it’s really the best option. Airlines and online agencies often offer widely varying prices for the same flight.
How to avoid it: Use a metasearch engine like Trabber, which compares prices across different websites and displays the final cost, including all fees. This way, you’ll avoid unexpected charges at the final booking step.

Additionally, when it’s more convenient, Trabber will suggest booking your outbound and return flights separately or recommend flights on nearby dates.
Conclusion
Booking a flight without mistakes is easy if you pay attention to details and use tools that help you compare and make the right choice. On our platform, we ensure you see the final price from the beginning so you can make an informed decision. Good luck with your search!
