A partial answer here.
Turkish Airlines allows cabin baggage up to 23x40x55cm, thus your rucksack has no issue.
What are the maximum dimensions and weight restrictions for my cabin baggage?
In Economy Class you can bring a single carry-on that must have dimensions of no more than 23x40x55 cm and a maximum weight of 8 kg. Business Class passengers can bring two pieces carry-ons that must each have dimensions of no more than 23x40x55 cm and a maximum weight of 8 kg. For more detailed information please visit our cabin baggage page.

The bag you show is bigger than the allowed dimensions on one JetAirways, and that pretty much answers your question. (The other answer says it's within limits on Turkish Airlines, so you should be fine if you manage to get it that far.)
I've never flown with those two airlines but, since the bag looks big, there's a good chance you'll be challenged about it. If it doesn't fit in one of their luggage measuring things, you won't be allowed to bring it as carry-on. If the bag is full, it won't fit, because it's too big. If it's not full, you'll probably be able to squish it into the measuring gauge – but if it's not full, that means you don't need such a big bag, so why not use a smaller one that meets the airline's rules?
