Flights from Prague to Heathrow: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew the route from Prague to Heathrow 
Verified travelerFlew with British Airways-Jul 2025
British Airways does not allow for check-in through app or website. There is a message that passports need to be scanned, but no way to do it. Check-in was unavailable at airport kiosks, so we had to do it in person at the desk. Not a huge deal, but allow plenty of time! Also a bit stressful if you want to choose/change/buy a seat as it is very last minute.
AnnaFlew with British Airways-Oct 2024
Dont get to Prague airport too early if you are checking a bag because they dont even tell you where you can go to check you bag until just a little before the flight. We sat and waited for no reason
Verified travelerFlew with British Airways-Jul 2024
The signs on posts in the Prague airport aren't tall enough, so if there are people in queue who happen to be in front of the signs, they're easy to miss. These signs are important to know which line one must use for ticketing: ticketing, bag drop, or level of passenger.
