MAN T1 to T2
I would leave an absolute minimum of 15 mins from leaving the EI plane to check-in desks in T2.
Leaving baggage reclaim in T1, walk past front of the Information desk and turn left passing the Post Office. Go out of terminal and take any of the three lifts on right hand side to Level 7 (Check this once inside the lift).
Follow signs for T2 which will take you along the Skywalk passing the rail station and the SAS Radisson hotel. If you are lucky, the travelators will be working but don't bank on it. You may enter T2 at arrivals level in which case you will need to go up one floor to the main check-in hall. There are a few check-in desks on the arrivals level but these seem to be mainly charter.
Hope this helps.
