The direct flight is always more convenient. It is not always worth the extra cost. The right answer depends on the price gap, the connection time, and what kind of traveller you are. Here's how to think through it.

When Direct Is Worth the Premium

City breaks under 5 nights. On a 3-night trip, a connecting flight that costs £40 less but adds 3 hours to each leg is a bad trade. You've spent 6 additional travel hours to save £40. That works out to worse than minimum wage, and you've eaten into the trip itself.

Travelling with children or anyone with mobility issues. Connections add physical and logistical complexity. The case for direct is strong.

No checked luggage buffer. With hand luggage only and a tight connection, a delayed inbound leg means a missed return. Direct flights eliminate this risk entirely.

High-value business or leisure time. If the time in transit matters, the premium makes sense.

When Connecting Is Reasonable

Price gap over £80-100 per person. A £100 saving for a 90-minute connection through a well-run hub is a reasonable exchange, particularly on longer holidays or multi-week trips.

The layover is at a good airport. Connecting through Amsterdam Schiphol, Zurich, or Vienna is low-friction. Connecting through a congested hub with a 70-minute window is not.

You have plenty of time. On a 7-night trip, losing 90 minutes on each end of the journey is less proportionally painful than on a 3-night break.

The direct option doesn't exist. Some European city pairs simply don't have direct services from regional UK airports. In that case, the question is which connection and which hub, not direct versus connecting.

The Connection Time Question

Minimum safe connection time varies by airport:

Short-haul within the same terminal, no checked bags: 60 minutes is workable at efficient airports. 45 minutes is uncomfortable.

Different terminals, same airport: 90 minutes minimum. Paris CDG terminal transfers can take 30-40 minutes alone.

International to domestic or Schengen to non-Schengen (or vice versa): Allow at least 90 minutes, ideally 2 hours. Passport control adds a queue with no guaranteed duration.

If your airline books you on a connection shorter than these windows, they take responsibility for rebooking if you miss the second leg because of a delay on the first. If you've booked separate tickets yourself, that responsibility is yours alone. This changes the risk calculus significantly.

The Hidden Cost of Connections

Connections on budget airlines almost always require separate bookings. Ryanair and easyJet don't interline with each other or with legacy carriers. If you miss a connection between two separately booked budget flights, you're buying a new ticket at last-minute prices.

On a city break budget, that risk can easily cancel out the savings from the cheaper itinerary.

The Practical Decision Rule

Direct flight if: the trip is under 6 nights, the price gap is under £80 per person per leg, or you're travelling with family.

Connecting flight if: the price gap is over £100 per person per leg, the connection time is 90 minutes or more at a reliable hub, the tickets are on a single booking (so the airline owns the connection risk), and the overall journey time is under 6 hours.

When in doubt, price out the direct flight and ask whether the saved hours are worth the cost difference in the context of the specific trip. For a long weekend in Lisbon, they usually are.
