Other European Frequent Flyer Programs - InterSky - experiences

There does not seem to be any thread with any info about InterSky, a small airline based at Friedrichshafen (FDH) on Lake Constance (Bodensee) in South Germany. They offer a small number of destinations, such as DUS, BER, VIE and a couple others.

As I needed to go to Bregenz (for the Bregenzer Festspiele), and they are the official carrier, I looked at prices from DUS, but they were far too high. But even right through September, October and November, it is impossible to get a seat in the cheapest seat category (EUR79). Do they release inventory at specific times, such as a special offer that appears from time to time?

They appear to offer full service, with free catering, bag check, and a EUR5 charge for seat selection. In the Vorarlberger Nachrichten newspaper of Tuesday of this week, it would seem that they plan to expand their fleet. Worth having a thread for all this?

The airline may be nice, I don't know. Two reasons for me not to fly them: As you mentioned, they are way too expensive. It's almost impossible to find low prices. Another reason to avoid is the airport Friedrichshafen which has no airport lounge. I prefer the much smaller airport of Altenrhein which is very efficient and comes with a very nice lounge.

Fair point. I find it impossible to get any sensible prices, even for dates in October and November, for DUS-FDH and back. However, flying into Altenrhein (ACH) is a pointless nightmare, as you can only approach it from and via Vienna. A miles ticket with Miles & More comes with EUR291 taxes attached: are they completely out of their minds??
