Munich isn't gone. It has a 6-week hiatus between the end of the summer schedule and the start of the skiing season. It's at lower frequency than last year then.
To be honest, I can't see the point in such a short break. It will just take passengers off the flights in October, making those less viable. Losing those passengers might be justified if you're avoiding 5 months unprofitable flying, but for 6 weeks?
