I had lots of flights in the DHC-7, all of them were operated by Arkia Israeli Airlines.
I flew with them:
TLV-RPN-KSW (only 6 min' between RPN & KSW!!!)
KSW-RPN-TLV (only 6 min' between RPN & KSW!!!)
All these routes are domestic lines inside Israel.
Arkia used to fly 12 of them, today IIRC they operate only 6 side by side with ATR72s, most of them are in the new Arkia c/s and they in good shape also from the inside.
Last June when I flew with Arkia from ETH to SDV on an ATR I spoke to the pilot and we compared the DH7 with the AT7, all in all, he said that those DH7s are more helicopters than a/cs...:D (all they need is 600 metters and they are airborned!!!)
The DH7 is known for it's reliablity, at Arkia they claim that it is the best a/c they have for bad weather, but soon enough they will all be gone....
