My flight arrives on a Tues in early October at 9:50am in which I will be seated toward the front of the plane in Premium Select on Delta. I will be taking the DB to Berlin. I don’t know what to anticipate with the lines at immigration & customs especially during the pandemic. I don’t plan to check luggage. How much time should I allow as I will also need to change terminals to catch the train. 2 hours? 3 hours? I cannot run. I actually will be using Wheelchair Service as I am not able to stand for long periods of time but I can walk.
Last question — when should I buy the ticket because I know schedules change yet I also want to get the Super Sparpreis of €26.90 for 1st class? Do I need to buy now? Thank you!
