01 / Follow the route
Fly into one city. Home from another.
When a trip moves in one direction, your flights can do the same.
A return ticket to the same airport is an easy starting point for a beach week or a single-city stay. For Barcelona to Seville or Rome to Venice, it adds a final journey back to where you began. Flying into the first city and home from the last is often called an open-jaw trip.
Compare the two arrangements as whole journeys. If returning to the first airport adds a train ticket, a hotel night and most of a day, those belong beside the flight price. A more expensive flight home from the last stop may leave you with a better holiday for a similar total.
Use a multi-city search when your booking provider offers one. Two one-way searches are another way to price the idea. A single booking can be more convenient to manage, while separate tickets can offer different airline combinations; their change and cancellation terms remain separate.
For the Spain route: home → Barcelona, then Seville → home. The train journey between them is part of the trip.
02 / Spend more time there
One flight in. More cities by rail.
The best airport for a trip is not always the one beside every stop.
Italy’s Rome–Florence–Venice route and Portugal’s Lisbon–Coimbra–Porto route work as continuous rail journeys. You can compare a wider choice of international flights at the ends without turning each move between cities into another airport day.
Think in terms of hotel-to-hotel time. A short flight still comes with a journey to the airport, time before departure and a transfer at the other end. A train arriving near the centre can leave more of the afternoon for the place you came to see.
An arrival day also has its own rhythm. Landing in Rome and sleeping there gives you an evening in the city before the route begins. If a separate train ticket follows your flight, the train operator’s missed-departure rules matter: a flight delay does not automatically move that booking to a later train.
Match the arrival airport to your first overnight stop. Match the departure airport to your last one.
03 / Make the first day count
Choose the arrival, not just the fare.
The same destination can feel very different at 2 pm and midnight.
For Bali, the flight ends at Denpasar but the first stay may be inland in Ubud. For a Croatian island trip, landing in Split is followed by a ferry journey. A low fare has less appeal if its arrival time leaves you needing an extra hotel or a long late-night transfer.
Read the full arrival date on overnight flights. The first night in your itinerary begins on the day you reach the destination, which may be the day after take-off. A daytime arrival can make the first hotel transfer simpler and leave time for a walk or dinner.
For Tokyo, both Haneda and Narita can serve the same holiday. Haneda is closer to the city, but the better choice depends on your flight times, fare and hotel neighbourhood. Compare the airport-to-hotel journey for each option instead of treating all Tokyo arrivals as identical.
A useful comparison has four parts: arrival date, landing time, onward journey and the first night’s stay.
