Flights between London and Prague: carriers, airports and fares

A fare that looks cheapest on a comparison site can turn into the dearest trip once you add a bag, a seat and the train out to a distant airport. London to Prague is a route with several airports and several airlines, and the choice is where the money is won or lost.

This guide explains what the choice involves. It does not quote fares, which change by the hour, and it does not recommend an airline.

The short version

Flights take about two hours in the air. Prague is one hour ahead of London all year, so a mid-morning departure lands in the early afternoon by Prague's clock (see our guide to time in Prague). Because the UK is outside the Schengen area, London flights land at Terminal 1, where passport control takes place, not at Terminal 2, which handles Schengen flights. The terminal rules are in our guide to Prague airport codes and terminals.

The London airports

Heathrow is the biggest airport and the natural home of full-service carriers. It suits travellers who want a hold bag and seat allocation included, and who live in west London or along the Elizabeth line.

Gatwick serves south London and the south coast, with both low-cost and traditional airlines.

Stansted is mainly low-cost and best for north and east London, East Anglia and Essex.

Luton is mainly low-cost too, convenient for north London, with a rail link and a short shuttle.

As a rule, the airport you can reach cheaply and reliably at the hour you need beats the one with the lowest fare. An early departure from Stansted may be out of reach of public transport, and a taxi cancels the saving.

The carriers

Airlines on the route include British Airways, easyJet, Ryanair and Wizz Air, but check timetables: carriers add and drop routes and airports with the season. This is a general statement, not a schedule. Check the airlines' own sites for your dates; a metasearch site shows the choices side by side.

The type of airline matters more than its name.

• Full-service airlines usually include a cabin bag, and often a hold bag, in the fare, and may offer a free drink or snack. Fares are often higher and change less.
• Low-cost airlines sell a bare seat, with a small personal bag allowed and anything else paid for, including cabin bags, seat selection, boarding priority and sometimes check-in at the airport. The headline fare is lower, but the final fare can match or exceed the full-service price.

Reading the real price

Price the whole trip. In a hypothetical example with abstract units, Flight A costs 40 for the fare, 30 for a cabin bag and 10 to reach its airport: 80 in all. Flight B costs 70, with a bag included and 5 for the transfer: 75. The flight that looked 30 cheaper is the dearer trip, unless you travel with only a small personal item, when A wins at 50.

So price your own trip, with your own luggage, from your own door. Include:

1. The fare for each direction, since the return can be a different airline.
2. Bags, seat selection and any fee to print or check in.
3. The cost and time of getting to and from each airport at the real departure hour.
4. The cost of reaching your Prague accommodation, which is covered in our guide to getting from the airport to the centre.

Border checks and documents

As a British citizen you enter Czechia as a visa-exempt visitor for up to 90 days in any 180 days, in the Schengen area as a whole, under the rule described in our explainer on Schengen 90/180. Passport issue-date and validity rules apply, so check the EU guidance before you travel. At the border you may be asked about the purpose of your trip and where you will stay. The EU's Entry/Exit System, which records non-EU short-stay visitors on entry and exit, has been phased in since October 2025, and ETIAS, a travel authorisation for visa-exempt visitors, is expected to follow (check the official EU site for the start date). Both are explained in our pieces on visa rules for visiting Czechia and ETIAS and Czechia.

Delays and cancellations

Passenger rights after a delay or cancellation depend on where the flight starts: UK rules for departures from the UK, EU rules for departures from the EU. Both give rights to care, such as food and accommodation in certain cases, and in some circumstances compensation for long delays. Thresholds and exceptions are set by the aviation authorities. Keep your documents, ask the airline for a written statement of the cause and check the official guidance before you claim.

Luggage and security

Cabin-bag sizes differ by airline, so check the dimensions on your booking confirmation. Rules on liquids in hand luggage follow the airport you leave from, differ between the UK and the EU and have changed over time, so check both ends.

When to book and when to travel

Fares tend to be lower when you book early and avoid weekends and school holidays, but no rule is certain. Flexible fares cost more and allow free changes. Prague peaks around the Christmas markets, Easter and the summer. Compare fares on the airlines' own sites, since some do not appear on every comparison tool.
