Just to clarify, I have been looking from DUS and CGN and have been wondering why dates from November on are greyed out. Of course, I eventually realised that flights from these cities are only to LIN during winter and there are far fewer flights from LIN to destinations around Europe. I did find MAD (via LIN) for €372 though, which is pretty good and saves the trip over to BRU (and it saves an overnight or two; on my last trip from BRU to VLC I needed an overnight in BRU on the outbound and one in FCO on the inbound, which raised the cost somewhat).

Where can I find a list of Alitalia destinations from LIN? I do wish the airlines would make proper timetables, even if only to download.
I was also wondering about more "exotic" destinations, like BEG and TIA. Also, TFS (Tenerife South) seems to be no longer served by Alitalia. AGP (Malagá) seems to be tricky to get generally. Other destinations? NCE, maybe?
