5 Mistakes When Buying a Flight Ticket That Can Ruin the Start of Your Trip

You found the ticket, the price looks good, and only one click separates you from payment. This is exactly the moment when it is worth slowing down. A wrong date, a different airport, missing baggage, a risky connection or restrictive fare conditions can turn a great deal into an expensive travel puzzle. The Travellizy team has collected five things worth checking before you press “Pay”.

When searching for flights, we naturally focus on two things: price and departure time. But the true cost and convenience of an itinerary depend on many more details.

A €70 ticket may end up being less attractive than a €95 ticket if the first one requires paid baggage, an expensive transfer from a distant airport or an overnight stay caused by a poor connection. That is why, before payment, it is better to evaluate not just the number on the screen, but the entire travel scenario.

Travellizy rule: a good flight ticket is not necessarily the lowest price. It is the best balance of cost, timing, baggage, airports, connections and fare conditions.

Mistake #1. Not Checking the Flight Date and Time

It sounds too obvious to get wrong. That is exactly why people do.

When comparing several dates, tabs and options, it is easy to switch to the next day, choose a midnight flight instead of an evening departure, or miss the fact that your arrival takes place on the following calendar day.

Be especially careful with flights departing around midnight. 00:30 on Tuesday means the night from Monday to Tuesday — not Tuesday evening. For an early departure, this may completely change the day you need to leave for the airport.

Before paying: read the itinerary once more as a sentence — “I depart on this date at this time, arrive on this date, and the trip lasts this many days.” It takes about 15 seconds and can prevent a very expensive mistake.

What exactly should you verify?

Check	What to pay attention to
Departure date	Make sure it is exactly the day you intended to travel.
Time	Pay extra attention to flights after 23:00 and after 00:00.
Return date	Make sure it matches your hotel booking, vacation length and plans.
Arrival date	On long-haul routes, this may be the next day or even later.

Mistake #2. Checking the City but Not the Airport

Seeing “London”, “Paris” or “Milan” in the search results does not mean all of the suggested flights will take you to roughly the same place.

Major cities and metropolitan areas may be served by several airports. London, for example, has six major international airports: Heathrow, Gatwick, Stansted, Luton, London City and Southend. Their locations and transfer times to central London are very different.

That is why a cheaper flight through a more distant airport does not always mean a cheaper trip. Add the transfer, travel time and possibly an early or late journey into the city, and the calculation may change completely.

Good habit: look not only at the city name, but also at the three-letter airport code — for example LHR, LGW, STN or LCY. Then check the route from the exact terminal to your hotel or meeting point.

London demonstrates this clearly: London City Airport is much closer to the center, while Stansted is approximately 64 km northeast of central London. So two options both described as “London” may involve completely different logistics after landing.

For current transfer information, it is best to check the official website of the specific airport or the city’s official tourism office.

Mistake #3. Seeing a Low Price and Not Checking the Baggage

One of the biggest mistakes when comparing tickets is assuming that “hand baggage” means roughly the same thing across all airlines.

In reality, the rules are set by the specific carrier, and the allowance may depend on the fare, travel class, route and even aircraft type. IATA explicitly notes that baggage allowances and conditions remain airline-specific.

The difference is easy to see in current airline rules. Ryanair includes one small personal bag up to 40 × 30 × 20 cm in all fares, and it must fit under the seat. A second cabin bag requires the appropriate additional option. On Lufthansa short- and medium-haul flights, the Economy Basic fare includes only a personal item up to 40 × 30 × 15 cm, while other Economy fares may also include a cabin bag of up to 8 kg.

In other words, two similar-looking prices can represent very different products.

What you see in search results	What to verify before payment
Low base price	What exactly is included in the fare.
“Hand baggage included”	Whether this means a personal item or a full-size cabin bag.
Baggage available as an extra	How much it costs for your exact route.
Several flight segments	Which baggage rules apply on each flight, especially when different airlines are involved.

Always verify the latest rules in your booking and on the airline’s official website. For general guidance, see IATA Passenger Baggage Rules.

Mistake #4. Looking Only at the Price of a Connecting Itinerary

A connection is not just a number like “1h 15m” between two flights. You need to understand how the itinerary is actually built.

First, check whether all segments are issued under one booking or whether you are looking at a self-transfer — an independent connection between separate tickets.

Why this matters: when flights are issued under one booking, connection protection may apply in many situations. In particular, EU rules concerning missed connections link the relevant passenger rights to flights that form part of the same reservation. With separate tickets, your level of protection may be very different.

With a self-transfer, you may need to collect checked baggage, pass through immigration and customs, change terminals, check your suitcase again and go through security another time. If the first flight is delayed, the next airline is not necessarily required to wait for you or rebook you for free.

Some itineraries may even involve an airport change. A search engine may technically display the journey as one itinerary with a connection, while in reality you have to travel across the city from one airport to another on your own.

A 90-minute connection can be perfectly fine — or a very bad idea

Everything depends on the scenario. One booking, the same terminal and baggage checked through to your destination is one situation. Separate tickets, passport control, baggage collection and a new check-in is another entirely.

Before booking a connection, check	Why
One booking or separate tickets	This may determine your protection if you miss the connection.
Terminals	Moving between terminals can require additional time.
Whether you need to collect baggage	With self-transfer, this often becomes your responsibility.
Whether the airport changes	You may need a separate ground transfer.
Transit and visa rules	Requirements depend on your nationality, transit country and whether you leave the international transit area.

Nationals of some countries may require an airport transit visa even when staying inside the international transit area of a Schengen airport. If the itinerary requires you to actually enter the Schengen Area — for example because your next flight is an intra-Schengen flight or you must leave the international zone — different rules may apply.

Before booking a complex connection, check the official visa requirements of the transit country. For Schengen, current information is available on the European Commission website.

Mistake #5. Not Reading the Fare Conditions

“Economy” has not meant the same product for every passenger on the same aircraft for a long time.

Airlines use different fare families: Basic, Light, Standard, Flex and others. They may differ in baggage, seat selection, date changes, refunds and additional fees.

That is why the cheapest fare is not always the best one, especially if your plans may still change.

Do not look only for the words “non-refundable”. Check the full conditions: whether date changes are allowed, what the fee is, whether you must pay a fare difference, what happens in case of a no-show and which extras are already included.

Lufthansa’s current fare structure, for example, shows how significantly different Economy fares can vary: some do not allow rebooking or refunds, while others permit them free of charge or for a specified fee.

Before paying, find the section called Fare conditions / Fare rules / Changes & refunds and spend a minute reading it. That minute can have a very real financial value.

One More Check We Would Never Skip: Passenger Name

It is not formally one of our five mistakes, but before payment, always compare the passenger’s first and last name with the travel document they will use.

Pay particular attention to transliteration, first-name/last-name order and accidental autofill errors. Name correction rules vary by airline: some carriers allow minor corrections, others charge a fee, and in some cases a new ticket may be required.

Thirty seconds before payment is cheaper than fixing the mistake afterward.

Travellizy’s Final Check Before Pressing “Pay”

You do not need to reread the entire booking page three times. Simply go through the itinerary from top to bottom and ask yourself five questions.

Check	Done?
Date: are departure, return, time and arrival day correct?	✔️
Airport: do I know the airport code, terminal and transfer options?	✔️
Baggage: do I know exactly what the fare includes?	✔️
Connection: is there enough time, with no unexpected self-transfer or airport change?	✔️
Fare: do I understand the change, refund and additional fee rules?	✔️

The Cheapest Ticket and the Best-Value Ticket Are Not Always the Same Thing

The biggest mistake when buying a flight ticket is judging an offer only by the first price shown in the search results.

A good itinerary takes into account not only the base fare, but also baggage, airport transfers, total travel time, connection risks and fare flexibility. Sometimes a slightly more expensive option saves money. Even more often, it saves time and stress.

At Travellizy, we recommend looking at the entire journey: compare routes, verify the details and only then decide which ticket is truly the best value for you.

Because the best start to a vacation is not the message “booking confirmed”. It is the moment when you do not have to open Google immediately afterward and nervously search: “how do I get from this airport to the city at 2 a.m.?”.

Information is accurate at the time of publication. Baggage rules, fare conditions, rebooking policies, transit requirements and visa rules may change and depend on the airline, itinerary, nationality and specific booking. Always check your ticket conditions and official sources before payment.
