Thinking of booking separate flights for a city break, and wondering what happens if one runs late?
Here's the honest version. Booking separate flights is normal. For a city break with a night or more in each city, it can work well.
The main risk is a missed flight. A delay or cancellation can make you miss an onward flight on a separate ticket, and neither airline has to put that right.
We reduce that risk by giving every multi-city trip a night or more, and at least 12 hours, in each city you stay in.
Most low-cost airlines in Europe sell each flight on its own. There's no return fare as such. A return is just two one-way fares added together.
So flying out to one city, on to a second and home from there costs what those flights cost. There's no penalty for not coming straight back.
Full-service airlines also sell connections through their hub airport, with both flights on one ticket. That's a different kind of trip. It's a change of planes, not a few days in each place.
On a short flight between two European cities, the cheapest option is often a direct low-cost one. That's sold on its own.
So a low-cost trip that takes in two or three cities means separate flights. That's how trips from Europe Unlocked work.
We're a search platform, and we don't sell flights. You book each flight directly with the airline.
This is the big one.
Sometimes two flights are sold together on one ticket. Here's what happens if a delay makes you miss the second:
✅ On one ticket: the airline generally has to get you to where you were going.
❌ On separate tickets: nobody does.
Say your first flight lands late and the second has already gone. The second airline treats you as a passenger who didn't turn up. You'll usually have to pay for a new flight.
On separate tickets, a checked bag isn't transferred to your next flight. You collect it, check it in again with the next airline, and go back through security.
With a night or more in each city, you'd be doing that anyway. On a same-day stop, it's time to allow for.
A multi-city trip can mean two or three different airlines. Each has its own cabin bag size, weight limit and price for anything bigger.
So a bag that's fine on your first flight can cost you extra at the gate on your second.
In general terms, the UK and the EU have similar rules for delayed and cancelled flights. They're often called UK261 and EU261.
Which one applies depends on where the flight leaves from and which airline operates it. Broadly, they cover flights leaving the UK or the EU. They also cover some flights arriving there, depending on the airline.
Say a flight is badly delayed or cancelled. Under those rules, the airline may have to look after you while you wait.
If it cancels, it has to offer you a refund or another flight. In some cases, it may have to pay compensation.
Compensation depends on things like how late you arrived and why. It isn't generally due when the cause was outside the airline's control.
Here's the point that matters for separate tickets. The rules apply to each flight separately.
The first airline's duties are for its own flight. They're judged against where that flight was going, not where you were heading next. So missing a separate onward flight isn't the first airline's responsibility.
The second airline hasn't let you down, so it doesn't owe you anything either.
We can't tell you what you're owed in a particular case. Each airline sets out its own process on its help pages. The CAA's website, caa.co.uk, explains the UK rules in plain English.
We can't stop a flight running late. What we can do is make sure an ordinary delay doesn't cost you your next flight.
Every multi-city trip in our search follows the same rules:
So no trip relies on a tight connection. A delay of a few hours should cost you some sightseeing rather than your onward flight.
It doesn't make the risk zero, though. A cancellation could still break the chain.
So could a delay long enough to push you into the next day, especially on a one-night stay. That's what the checklist below is for.

Separate flights work well with time between them. They work badly without it.
Say you land at one o'clock for a separate flight at three. That only works if everything goes right. You need an on-time arrival, a quick walk out, check-in again and security again.
One late departure and the plan's gone. Our trips don't do this. The shortest gap on any trip is 7 hours, on a same-day stop.
Say what comes next is a long-haul flight, a cruise or an event you can't miss.
Landing at one airport and leaving from another in the same city adds a transfer to the gap. Some cities have more than one airport, so check the airports, not just the city. Every trip shows where it lands.
📌 Key points
- Booking separate flights is normal, and can work well with a night or more in each city.
- The main risk is a delay or cancellation making you miss a separate onward flight. Neither airline has to put that right.
- Your passenger rights cover each flight on its own.
- Every multi-city trip we show has a night or more and at least 12 hours in each city you stay in, or at least 7 hours on a same-day stop.
For a trip with a night or more between flights, it's normal and can work well.
The risk is greatest with tight connections. A delay on one flight can make you miss the next, and neither airline has to put that right.
It's changing planes on separate tickets, and moving yourself and your bags between them. The airline doesn't do it for you.
On a trip from us, you're never rushing between gates. There's a night or more in each city you stay in, or at least 7 hours on a same-day stop.
Usually you. The first airline owes what the rules say for its own flight. The second airline owes nothing for a flight you didn't reach.
