A flight can cost less than the taxi from the airport to your hotel. Both prices may be genuine—the problem is that one appears prominently during booking, while the other remains hidden until later.
To travel for less, compare the cost of the entire journey rather than the headline airfare or nightly room rate. Include baggage, airport transport, transfers, foreign-currency charges, mobile data and insurance. The cheapest initial offer can become expensive once essential extras and financial risks are taken into account.
1. Comparing headline prices instead of total trip costs
Start with a like-for-like calculation for every option. Include:
- Tickets for all travellers
- Cabin or checked baggage in both directions
- Transport to and from the departure airport
- Parking or an airport hotel, if required
- Transport from the arrival airport
- Seat selection or other services you genuinely need
- Payment, booking or currency-conversion costs
In the EU, advertised flight prices must include unavoidable and foreseeable taxes, fees and charges, while optional services must be presented separately. That does not mean the cheapest displayed fare includes checked baggage, preferred seats or flexible changes. ([europa.eu](https://europa.eu/youreurope/citizens/consumers/shopping/pricing-payments/index_en.htm?utm_source=openai))
A low-cost carrier is not automatically the cheapest choice, just as a full-service airline is not necessarily more expensive. Compare the final usable product, not the promotional number.
2. Adding baggage after booking
If you already know that you need a larger cabin bag or checked luggage, include it when comparing fares. Do not select a basic fare on the assumption that you will solve the baggage question later.
Travellers sharing a room may not need one suitcase each. Two people can sometimes share a checked bag, provided its contents comply with the airline’s weight, size and restricted-item rules. Leave space for anything you expect to bring home.
3. Assuming every airline has the same cabin-bag rules
“Cabin baggage” is not a universal size category. A bag accepted by one carrier may be oversized—or treated as a paid item—by another.
Check the rules for your specific airline and fare shortly before departure. Measure the bag at its widest points, including wheels, handles and external pockets, and weigh it after packing. On the return journey, account for souvenirs and other purchases.
Security restrictions and airline baggage allowances are separate matters: an item may be permitted through security but still exceed your carrier’s size or weight limit. ([europa.eu](https://europa.eu/youreurope/citizens/travel/carry/index_en.htm?utm_source=openai))
4. Building a connection from separate tickets
Combining unrelated bookings can produce an attractive fare, but it also transfers more risk to you. If the first flight is delayed and you miss the second, the next airline will not normally treat the journey as a protected connection simply because the flights appeared together in your search results.
EU missed-connection protection, where applicable, depends in part on the connecting flights being included in a single reservation. Separately purchased outbound and return flights can create a similar problem: cancellation of one booking does not automatically make the other refundable. ([europa.eu](https://europa.eu/youreurope/citizens/travel/passenger-rights/air/index_en.htm?utm_source=openai))
For a self-transfer, allow time for immigration, baggage collection, terminal changes, security and check-in deadlines. Consider whether the saving would still be worthwhile if you had to buy a replacement flight or pay for an unexpected hotel night.
5. Choosing a remote airport without pricing the transfer
An airport marketed with a major city’s name may be many kilometres from the place you intend to visit. A cheaper flight can therefore come with a longer or more expensive transfer.
Before booking, check:
- The airport’s actual location
- Public transport fares and journey times
- The final evening departure
- Taxi or ride-hailing prices
- Whether your accommodation allows late check-in
- The cost of travelling back to the airport
A remote airport can still be economical, particularly for a group sharing a transfer. It only becomes a genuine bargain after the ground-transport costs are included.
6. Automatically choosing a non-refundable rate
A non-refundable flight or hotel can be sensible when your dates are firm and the saving is meaningful. It is less attractive when the trip depends on leave approval, health, visas or several people coordinating their schedules.
Read the conditions rather than relying on labels such as “flexible”. The ability to change a date may not include a refund, and a waived change fee may still leave you paying a fare difference. Compare the extra cost of flexibility with the amount you could lose if plans change.
If you are booking several services, also compare independent reservations with a genuine package. Qualifying packages sold in the EU provide protections that do not generally apply to stand-alone flights and accommodation booked separately. ([europa.eu](https://europa.eu/youreurope/citizens/travel/holidays/package-travel/index_en.htm?utm_source=openai))
7. Paying in your home currency without checking the exchange rate
A card terminal abroad may offer to charge you in your home currency rather than the merchant’s local currency. This is commonly called dynamic currency conversion, or DCC.
The familiar currency may feel reassuring, but the displayed amount includes a conversion chosen by the merchant or its payment provider. Your card issuer does not perform that conversion. Paying in the local currency usually lets your card network and issuer handle the exchange instead, although your account may still impose a foreign-transaction or conversion fee.
Before travelling, check your card’s exchange-rate policy and foreign-use charges. At the terminal, read the options carefully and do not allow staff to choose a currency without your agreement.
8. Accepting an ATM’s conversion—or ignoring its fees
Foreign ATMs can add costs in several ways. The ATM operator may charge a fixed access fee, your bank may impose a withdrawal fee, and the machine may offer its own currency conversion.
If you decline the ATM’s conversion and request the withdrawal in local currency, your card network and issuer normally handle the exchange under their own terms. Read every screen before confirming. If the machine discloses an unacceptable operator fee or exchange rate, cancel the transaction and try another ATM.
Avoid withdrawing excessive cash solely to pay a fee fewer times. Unused cash may be costly to exchange again, while carrying a large amount increases the consequences of loss or theft.
9. Assuming your mobile plan works everywhere
Check the roaming status of every destination, including countries visited during a stopover. Geographic proximity does not guarantee that two places belong to the same roaming zone.
For customers of EU mobile providers, regulated “roam like at home” coverage applies across the EU and European Economic Area, as well as Moldova and Ukraine. Fair-use limits can still apply, particularly to plans offering large or unlimited domestic data allowances. Other destinations, including the UK, may be included voluntarily by individual operators but are not automatically covered by the EU regime. ([europa.eu](https://europa.eu/youreurope/citizens/consumers/internet-telecoms/mobile-roaming-costs/indexamp_en.htm?utm_source=openai))
Outside your plan’s included area, compare an operator travel pass with a local SIM or eSIM. Download offline maps and essential booking details before departure so that you are not dependent on airport Wi-Fi.
10. Leaving mobile data active on a ship or aircraft
A phone on a ferry, cruise ship or aircraft may connect to a non-terrestrial network using satellite equipment. These services can fall outside ordinary roaming protections and may charge much higher rates.
EU roaming price rules do not cover satellite-based onboard networks, even when the vessel is travelling between EU destinations. European consumer guidance recommends disabling roaming or activating flight mode while on board. ([europa.eu](https://europa.eu/youreurope/citizens/consumers/internet-telecoms/mobile-roaming-costs/indexamp_en.htm?utm_source=openai))
If you want to use onboard Wi-Fi, connect deliberately and review the price and data allowance first. Be careful near coastlines and borders too, where a device may select a network from a different territory.
11. Treating a public healthcare card as travel insurance
Reciprocal healthcare arrangements can be valuable, but they rarely replace comprehensive travel insurance.
For example, the European Health Insurance Card gives eligible travellers access to medically necessary state healthcare during temporary stays under the same conditions as locally insured patients. It may not cover private treatment, and local patient contributions can still apply. ([europa.eu](https://europa.eu/youreurope/citizens/health/unplanned-healthcare/ehic/index_en.htm?utm_source=openai))
An EHIC also does not provide broad cover for disrupted travel, stolen belongings or every form of medical repatriation. Travellers should understand what their healthcare arrangement covers and consider separate insurance for the remaining risks.
12. Choosing travel insurance on price alone
The cheapest policy may be adequate, but its price means little without the coverage details. Check:
- Emergency medical-expense limits
- Medical evacuation and repatriation
- Excess or deductible amounts
- Trip duration and geographical limits
- Cancellation and interruption conditions
- Existing-condition exclusions
- Baggage and valuables limits
- Cover for planned sports and activities
Insurance included with a bank account or payment card also requires scrutiny. It may need to be activated, apply only when the trip is paid for with that card, cover limited journey lengths or exclude some travelling companions.
Do not merely ask whether you have insurance. Ask who is covered, where it applies, how long it lasts and which situations are excluded.
A six-question check before you pay
Before confirming a booking, answer these questions:
- What is the total cost, including baggage and airport transfers?
- Are all connecting flights on one reservation?
- What happens if the dates change or the first service is delayed?
- Which exchange rates and foreign-use fees will my cards apply?
- Does my mobile plan cover every destination and form of transport?
- What exactly is covered by healthcare arrangements, travel insurance and card-linked benefits?
The cheapest holiday is not necessarily the one with the lowest advertised price. It is the trip whose total cost you understand—and whose remaining risks you have consciously decided you can afford.

I’m most interested in technology, the internet, bizarre news, and stories that make you stop and think, “There’s no way this can actually be true.” I follow what’s happening both at home and around the world and pick the topics I think are worth paying attention to. On Pitchoviny, I try to present them simply, factually, and without unnecessarily sensational headlines.
