I will travel by train to Frankfurt Airport very early in the morning (2 am) and I have a big check luggage. The check-in counter for Vietnam Airlines (I will fly to Hanoi, Vietnam) will be opened (around 11 am) before the departure at 1 pm and it is so long time to stay with this big luggage until the counter is opened as I just want to inside the Airport early through passport control and rest on a sofa.
Does the Frankfurt Airport has a service (e.g: self-service kiosk for all Arlines) which one can drop the check in luggage on the same day of the flight out and it is automatically sent to the cabin of his flight?
