In case of late arrival, and I do not have enough time for the next flight, what can I do ?

As long as your connecting on the same airlines you are fine as the terminals are the same for connecting airlines. May be a good 10-15 min walk. Otherwise good luck.

I would talk to your airline ticketing counter at the airport and see where they could arrange a different correcting flight for you... if it was a transfer to a plane in the same airline, they have to accomodate you and guarantee your destination...
