Short answer: in winter be at the Pulkovo check-in desks 2.5 to 3 hours before departure, not two. The airport recommends at least two hours, and on a calm autumn day that is plenty. In a snowstorm you also inherit a jammed Pulkovskoye Shosse, a queue at entrance screening, and de-icing of your aircraft.
One number does not move: check-in at Pulkovo closes no later than 40 minutes before departure. That is the airport's own rule, and it applies in July and in a blizzard alike. Boarding closes even earlier — the exact time is set by the airline and printed on your boarding pass together with the gate number.
Budget three separate blocks of time
Most people who miss a flight counted only the drive. Count three stretches instead, and in winter all three stretch further.
Getting there. Forty minutes from the centre in summer, up to 90 minutes in heavy snow. There is one interchange serving the airport and no realistic way around it.
Entrance to desk. Security screening at the terminal door, finding your airline, bag drop: 20 to 30 minutes normally, twice that on a day with backed-up delayed flights.
Desk to gate. Screening, passport control on international routes, and the walk: allow 30 minutes at least.
Add it up and you get roughly three hours door to gate. Leave the city centre 3.5 hours before a domestic flight and 4 hours before an international one.

Getting to the airport when it snows
Buses are the predictable option. Route 39 runs from Moskovskaya metro with all stops, every 5 to 7 minutes, from 05:15 to 01:36. The express 39E runs every 13 to 20 minutes from 06:00 to 01:40. Route 82E connects the airport with Prospekt Veteranov metro every 15 minutes, 06:00 to 01:40. A single ticket on any of them costs 88 roubles; with a Podorozhnik travel card a surface-transport ride costs 65 roubles in 2026. There is a Podorozhnik kiosk on the forecourt, open 08:00–20:00 with a break from 13:00 to 14:00. Full route details are in our guide on getting from Pulkovo to the city centre.
Taxis cost more in a storm and do not move faster. If you drive, note the kerbside rule: 15 free minutes, no more than once every 30 minutes, after which the transit-zone tariff of 2,000 roubles per half hour applies. Parking as of October 2026: P1 costs 1,100 roubles an hour or 2,100 a day; P2 charges 450 roubles per 30 minutes; long-stay P4 is 1,100 roubles for the first day, then 900, 800 and 700 per day, a 10–12 minute walk away. A free 120-space car park sits 3 km off on Pulkovskoye Shosse.
De-icing and delays
Ice on the wings changes their profile, so the aircraft cannot take off until it is sprayed with a hot glycol mixture. That takes minutes per plane — but in real snowfall every departure needs it, the rigs are finite, and a queue forms. Holdover time is limited too, so a long wait for take-off can send the aircraft back for a second pass. Pulkovo states plainly that in bad weather de-icing affects flight handling times.
Practical consequence: treat winter delays as normal. Never book a one-hour connection in January; three hours is the realistic minimum. If your flight is already late, read our guide to delays, cancellations and backup plans, and claim what the airline owes you — drinks, meals, and a hotel on long waits.
Watch the flight, not the loudspeaker
Check the departures board on the airport website before you leave home, keep airline notifications switched on, and look at the weather where your inbound aircraft is coming from. One trap to avoid: seeing a two-hour delay and leaving later. Delays shrink, aircraft get swapped, and the 40-minute check-in cut-off is never extended for you.
