How to save on flights to and within Italy (2026)

The ticket price is not the flight price

A 19.99 euro flight can turn into a 90 euro flight before you board. The final price depends on five items: the base fare, baggage, seat selection, transfer from the airport and the risk of mistakes (wrong name, forgotten check-in, oversized bag). People who really save do not look for the lowest fare: they compare the total cost of the trip, from your front door to the hotel. This guide, updated in November 2026, gives you the numbers to do that. Airline fares change often: before paying, always check the figure on the airline's website.

When to book

There is no magic day, but a few rules hold up. Expedia's 2026 report on air travel puts the best average window for domestic economy flights at 31 to 45 days before departure, and 15 to 30 days for international ones. Those figures come mostly from the North American market: in Europe, for flights to Italy in high season, it pays to move earlier, roughly 2 to 4 months ahead for July, August and long weekends, and 4 to 8 weeks ahead in quiet months.

Other numbers from the same study: Friday is the cheapest day to fly (about 18% less than Saturday), Tuesday is the least crowded day, June is the cheapest summer month and August the busiest. Sunday comes out as the cheapest day to buy, but the gap is small and varies from route to route.

Three practical rules:

For fixed dates (weddings, exams, long weekends) book early: prices almost always rise as departure nears.
For flexible dates, set a price alert and buy when the fare drops below your threshold.
Search the whole month, not a single day: moving by one day can save 20 to 50 euros.

Cabin bags in 2026: the rules of five airlines

Baggage is the first source of surprises. The ENAC limit of 115 cm (sum of the three dimensions) applies to everyone, but each airline sets its own sizes and weights. Here are the main figures for 2026, to be checked when you buy.

Ryanair: one free bag under the seat, 40x30x20 cm. The 55x40x20 cm, 10 kg trolley requires Priority, from about 12.49 to 36 euros online. At the gate the penalty can reach 70 to 75 euros.
easyJet: one free bag under the seat, 45x36x20 cm. The large cabin bag, 56x45x25 cm (up to 15 kg), is paid, with a price that varies by route, or included in Up Front and Extra Legroom fares and in easyJet Plus.
Wizz Air: one free bag, 40x30x20 cm. The 55x40x23 cm, 10 kg trolley requires WIZZ Priority, from about 4 to 40 euros online. At the gate the penalty runs from about 30 to 60 euros.
ITA Airways: one bag of 55x35x25 cm and 8 kg plus a personal item of 45x36x20 cm. Watch out for the Economy Light fare, which does not include a checked bag. According to the sources we consulted, ITA does not charge a gate penalty for an oversized cabin bag: it puts it in the hold.
Volotea: one free small bag under the seat. The 55x40x20 cm, 10 kg trolley requires priority boarding, from about 9 euros, or a higher fare. At the gate the penalty is about 65 euros.

Practical rule: buy the bag online when you book, because at the gate it costs three to five times more. Measure your bag including wheels and handles, weigh it full, and choose a soft backpack, which squeezes in better than a rigid trolley. Checks are stricter from June to September and at busy airports such as Bergamo, Bologna, Catania and Palermo.

Alternative airports: further away, often cheaper

Low-cost airlines use secondary airports, where fees and costs are lower. The saving on the flight must be weighed against the cost and time of the transfer. For a full list of airports and connections, see our page on Italian airports.

Milan: Linate is the most convenient, connected to the centre by the M4 metro with an urban ticket of about 2.20 euros. Bergamo Orio al Serio is about 50 km from Milan: buses to Milano Centrale take 50 to 60 minutes and cost 4 to 10 euros. Malpensa is served by the Malpensa Express train.
Rome: Fiumicino is the main airport. Ciampino, used by Ryanair and Wizz Air, is about 15 km from Rome, and buses to Termini take about 40 minutes and cost about 6 euros.
Venice: Treviso is about 31 km from Venice. The ATVO bus to Piazzale Roma takes 50 to 70 minutes and costs 12 euros one way (22 euros return). Marco Polo is closer but usually more expensive.
Florence: the city's own airport is small, with few routes. Many travellers choose Pisa, linked by frequent trains (about an hour to Firenze Santa Maria Novella), or Bologna, from where the fast train reaches Florence in about 35 to 40 minutes.
Western Sicily: Trapani Birgi, used by Ryanair, is about 15 km from the town and over 100 km from Palermo, with direct buses. In the south-east, Comiso is the choice for Ragusa and Modica (about 20 km), while Noto and Syracuse need about an hour and a half by road. Always check real distances before booking.
Salento: Brindisi is the main airport for Lecce, about 40 km away, with buses and trains. Bari is much further.

A simple test: the secondary airport pays off if the flight saving, for all travellers, is more than the extra transfer cost, and if the timing lets you use ground transport (the last buses often leave early after evening arrivals).

Plane or train: domestic routes

On the main routes the high-speed train beats the plane once you count total time. Approximate times and average prices, November 2026:

Rome-Milan: train about 3 hours centre to centre, prices from 29.90 euros, with many daily services between Trenitalia and Italo. Plane Fiumicino-Linate: 1 hour 10 minutes in the air, but with transfers and security it is 4 to 5 hours centre to centre. The average fare given by the sources is around 107 euros, from about 36 euros for the lowest fares.
Milan-Naples: train about 4 hours 20 minutes, plane about 1 hour 25 minutes in the air. Here the plane starts to make sense if you find a low fare and have no hold luggage.
Rome-Venice: train about 3 hours 45 minutes; the plane is hardly competitive once you add transfers to Mestre or Venice.

The train wins under 3 hours 30 minutes, because there is no security check and it drops you in the centre. The plane wins when the train takes over 4 hours, or when the fare is very low. Book trains at least 30 days ahead for the best deals. For other trips, see our guide to the cost of a trip to Italy.

The islands: territorial continuity for Sardinia and Sicily

Territorial continuity (continuità territoriale) is a public scheme that regulates fares and frequencies on flights to and from the islands, to guarantee the right to mobility.

Sardinia. The new regime started on 29 March 2026 and runs for three years. It links Cagliari, Olbia and Alghero with Rome Fiumicino and Milan Linate. Subsidised fares are about 30 euros to Rome and 44 euros to Milan one way, excluding VAT and airport charges, which means about 118 to 119 euros return for Cagliari-Rome and 136 to 159 euros return on the Milan routes, taxes included. Eligible are: Sardinian residents, workers with a stable base on the island, military personnel based there, students up to 27, young people aged 2 to 21, people over 70, people with disabilities and their companions. Relatives up to the third degree of residents and people caring for relatives under Law 104 pay about 30% more than residents. Eligibility is self-declared at purchase. A tourist with no family ties pays the market fare.

Sicily. There is no single regime as in Sardinia. Palermo and Catania are not covered; instead there are resident discounts funded by the Region, extended to 30 November 2026, which participating airlines (including Wizz Air and Aeroitalia) apply at the time of purchase. True territorial continuity concerns the smaller islands: Lampedusa and Pantelleria, with the mandate extended to 31 October 2026. For percentages and routes, check with the regional body or the airline.

If you are not eligible for the subsidised fares, compare several airlines and airports: summer market fares to the islands can be far higher than the subsidised ones.

Your rights: EU Regulation 261

If your flight departs from an EU airport, or lands in one on a European airline, Regulation (EC) No 261/2004 gives you precise rights.

Cancellation: a refund of the ticket within 7 days or an alternative flight, plus assistance (meals, a hotel if needed). You are also owed compensation if the airline tells you less than 14 days before departure, unless there were extraordinary circumstances.
Arrival delay of more than 3 hours: compensation of 250 euros for flights up to 1,500 km, 400 euros between 1,500 and 3,500 km, 600 euros over 3,500 km. For a domestic Italian flight the amount is 250 euros.
Denied boarding because of overbooking: compensation at the same amounts, plus a refund or alternative flight.
No compensation if the delay is caused by extraordinary circumstances, such as severe weather, air traffic control strikes or political instability. An ordinary technical fault, however, is normally not one.

How to claim: write to the airline using the official form on its website, and keep your boarding pass, emails and receipts for expenses. If they do not reply within 6 to 8 weeks, or they refuse, complain to ENAC, the Italian passenger-rights authority. For disputes there are conciliation and the small claims judge. Be wary of services that keep 25 to 35% of your compensation: you can do it all yourself for free.

News: in June 2026 the Commission, Parliament and Council reached an agreement on a revision. Thresholds and amounts remain unchanged, while airlines will have to inform you of your rights within 96 hours. The new rules will apply 12 months after official publication, so for now the current regulation still applies.

Mistakes that cost money

A name that differs from your document: the name on the ticket must match your passport or ID card. Correcting a mistake can cost anything from a few dozen euros to nearly the price of a new ticket, depending on the airline.
Checking in at the airport: low-cost airlines ask you to check in online and use a digital boarding pass. At the airport it can cost a lot, with fees of around 55 euros per person on some airlines.
Oversized or overweight bags: see above, 30 to 75 euros at the gate.
Useless insurance: cover offered during booking often repeats what you already have with your credit card or under EU261. Check first, and only buy health cover if you travel outside the European Union.
The wrong airport: "Milan" can mean Malpensa, Linate or Bergamo, with 50 km of difference.
Opaque online agencies: if a flight is cancelled, the refund goes through the intermediary, which takes longer. Book directly with the airline if you have doubts.
Connections on separate tickets: if the first flight is late, the second is not protected.

Tools to track prices

Google Flights: price calendar, whole-month graph, price alerts and the Explore function to search "anywhere".
Skyscanner and Kayak: comparison of several airlines, "whole month" search and email alerts.
Airline websites: Ryanair and Wizz Air do not always appear on every comparison site, so always check directly.
Trains: Trenitalia and Italo, with alerts for alternative routes.

Set an alert for your dates and re-check the baggage price when you buy. After landing, an eSIM or an arranged transfer avoids extra costs: see our guides.

Five tips to spend less

Compare the total cost, not the base fare.
Buy bags and seats online, never at the gate.
Consider an alternative airport, but work out the transfer.
If the train takes under 3 hours 30 minutes, take the train.
If the flight has problems, claim EU261 compensation without intermediaries. To choose the right month, see our page on when to go to Italy.
