I am traveling with LAN Airlines this weekend. I'll take a flight from Madrid to Frankfurt but I don't know from which terminal my flight departs or which terminal my flight arrives to. My ticket only states that the flight takes off from Madrid and lands in Frankfurt.

I guess that this information will appear in the boarding pass but I was wondering if there is any way of knowing it in advance (besides sending an email to the company which I have just done).

I've been looking and I've found that the main offices of LAN Airlines in Madrid are in the T4 terminal but I don't know if their flights take off from here or from the older terminals.

Does anyone know which terminal do LAN flights take off from in Madrid and to which one they arrive in Frankfurt?
