Cheap flights: how to compare real deals, not just the lowest price

Regulation (EC) No 1008/2008 requires the final price of a flight to always include the fare plus all taxes, airport charges and mandatory, foreseeable surcharges at the time the price is published. That’s the rule behind why a comparison site can’t just show the single lowest number without the items that come with it: in the 2017 Air Berlin case, the Court of Justice of the European Union confirmed that the fare and charges must be presented separately from the very first price screen, not added as a surprise later in the purchase process.

Optional extras follow a different rule. Travel insurance, seat selection, baggage beyond the included allowance: EU rules require these to be communicated clearly from the start of booking and accepted on an opt-in basis, meaning through an explicit customer action. A box already ticked for insurance doesn’t meet that standard, which is why it’s worth scrolling through every screen of the purchase process before confirming.

Cheap flights: from the comparison site to the airline’s own page

A comparison site remains the fastest starting point for a first look at prices across a range of dates: it ranks fares with an algorithm that compares them against each other, not against the final price you’ll actually pay. Its limit is that it almost always shows the lowest possible fare, often without checked baggage or an assigned seat: a second check on the airline’s own site, for the same flight and dates, shows whether the price still holds once the extras you actually need are added.

Practical example: a comparison site shows a flight at €39. On the airline’s own site, for the same time slot, the base fare is the same, but adding a 20 kg checked bag and a window seat brings the total to €78. Another airline, with a starting fare of €49, already includes a larger bag in the price: the comparison is worth making after adding up the items you’ll actually use, not on the first number shown.

Shifting the dates by a few days, or looking at a nearby airport instead of the most convenient one, often changes the price more than the airline’s name does. Anyone packing for a longer trip also runs into other practical rules on board, like the ones on carrying a power bank on a plane: logistics that add to the price comparison without replacing it.

Finding cheap flights that stay cheap: baggage and taxes included

In July 2026, the Council of the European Union gave its final clearance to a reform of air passenger rights that includes free carry-on baggage up to 100 cm total size and 7 kg, to be included in the base fare at no extra cost. The political agreement between the Council and the European Parliament, the two institutions whose workings are covered in more depth in how the European Union works, had been reached on 15 June 2026; the Council’s final clearance followed on 13 July 2026. The new rule, however, only takes effect twelve months and twenty days after official publication in the Official Journal of the European Union, a date not yet known at the time this Recap was written: until then, each airline’s own baggage policy still applies, and it varies a lot from one carrier to another.

Item	Included in the base fare shown by a comparison site	Check separately
Fare and airport taxes	Yes, by law	—
Small personal item (under the seat)	Almost always	Maximum size differs between airlines
Cabin bag (over 100 cm/7 kg)	Rarely	Extra cost, if not included
Checked baggage	Rarely	Weight and price vary widely
Seat selection	Rarely	Optional extra, opt-in
Travel insurance	Never by default	Optional extra, opt-in

When a flight falls through: cancellations and delays

For a flight that’s cancelled, or delayed more than three hours from the scheduled time, EU passenger rights rules provide for compensation between €250 and €600, depending on the route’s distance. It’s a protection that has been in force for some time, and the Council of the European Union’s press release of 13 July 2026 confirms it without changing it: the 2026 reform adds new rights, such as free carry-on baggage, but doesn’t touch the compensation thresholds already in place.

Hotel deals: cancellation and rates, not just the price

According to the European Consumer Centre Italy, a hotel booking remains valid even without any advance payment, but the freedom to cancel it depends entirely on the rate chosen at booking. Non-refundable rates, cheaper, commit the customer to paying for the full stay even if they cancel; cancellable rates, pricier, leave a window to change their mind without a penalty. Many hotels apply penalty percentages that grow the closer the stay gets, up to 100% of the amount for a last-minute cancellation, but those penalties must exclude the cost of ancillary services not used, such as breakfast.

Anyone who wants to keep both options open, the lower price and the ability to cancel, can look at travel insurance that covers cancellation penalties: an added cost that’s worth weighing against the price difference between the two rates.

Practical example: two people book the same room for the same weekend. The first chooses the cancellable rate and pays €140, with the right to cancel for free up to two days before. The second chooses the non-refundable rate and pays €110. If plans change at the last minute, the first gets the full amount back, the second doesn’t: they agreed to that condition at the time of booking.

If the room assigned doesn’t match the listing, the source advises complaining immediately and on site, documenting the problems with photos or written reports to staff: a timely complaint makes it easier to claim compensation afterwards, compared with a complaint made only after checkout.
