My flight arrives at 14.35 at terminal T2, do I have enough time to catch the AVE train to Oviedo from Chamartin station at 16.37? I think 2 hours is enough for bus transport between terminals T2 and T4 and train (cercenias)?
This is such a frequent question (but that won’t stop me from giving an opinion), and you can be sure that you will get opinions on both sides. That’s because it’s impossible to know whether you will make it till the day you try. You’ve got a good idea about what you need to do to get there. Hopefully you are not checking luggage.
Just for fun, I’ve tried to lay out every segment — from getting off the plane in T2 to arriving at Chamartín. If you think about it this way, step by step, you can see that 2 hours is in the “maybe” category, while 3 would be pretty safe.
Get off plane (depends on how far back you are, and the differences may be as much as 15 - 30 minutes minutes from front to back).
Get to immigration (depends on how close your landing gate is to immigration) (5-10 minutes)
Go through immigration (depends on how many other planes have just landed and how big they are). (5-?????? minutes)
Get luggage (hopefully you can omit this step)
Get on bus from T2 to T4 (run every five minutes during day and evening and every 20 minutes overnight; trip itself reliably takes about 20 minutes). (25-30 minutes)
Get off bus and down to Cercanías - (5 minutes plus buying ticket may be confusing if you’re a first timer).
Get on Cercanías and get to Chamartín - trains run every 15 minutes and take about 12 minutes.
Get from Cercanías to waiting room where they will announce the track number for your train to Oviedo. 2 minutes.
If all goes well, you can make it. To give you hope, my record time from getting off the plane to drinking a coffee in Chamartín was 40 minutes, in 2022 (but I always land in T4 so you would have to add time from T2):
I got off the plane at 6:35 and by 7:15 I had been through immigration, taken the train to the main terminal T4, gone through the vaccination check, taken the commuter train to the Chamartin train station, and was drinking my first cafe con leche.
When I connect from Barajas to a train station, typically buy a ticket with a comfortable transfer time, but make sure that I can change it to an earlier train if I am lucky.
