N27XJ is the pride of the fleet
It is the oldest plane in the fleet and will likely go back to the leasing company sooner or later (more likely the dumpster). I thought it was already returned but sure enough, I worked a flight on it the other night. Oh well. 27 was certified in 1985. It was the 27th Saab 340 to roll off the line. That is as old as my sister!
In re: all the hardstanded DTW Saabs, in recent times things have gotten slower for the Saabs. Some of the Saab routes have been pretty much been replaced by Pinnacle's CRJ's. I don't know about out of DTW, but here at MSP you are seeing ever-growing banks of CRJ flights, some cutting into routes that were always XJ strongholds, such as MSP-RST, MSP-CWA and MSP-DLH. And you get a day like Saturday which is a bit slower than the rest and you are going to find less need for the capacity. The lowered fleet utilization isn't all that great, but when you need a spare to replace a broken plane or a B+ model because an A model won't do the job, it's kind of nice sometimes.
As far as 9E Saabs, I've seen at least ten of their Saabs around, I can't remember what the highest a/c # is that I've seen around though. The fleet even includes the notorious N366PX, the same one that was kindly parked in a ditch at MEM one evening.
Oh and we do have some attractive young flight attendants. And quite a few attractive female pilots as well
