It is completely impossible to know what the situation will be mid-April. We may be in a global pandemic situation with all flights cancelled worldwide, or it may all have died down.
What you can see is the current status of flights these days, on Flightaware for instance.
You'll see that at time of writing, it's a mixed bag:
- many recent/upcoming flights have been cancelled
- many recent/current flights are flying or have flown
- many upcoming flights are still scheduled, but that can of course change at any time.
It looks like Turkish Airlines are the most susceptible to cancelling the flights altogether in this situation, but it's still pretty hard to tell (and things can change in the coming hours).
Right now, it will be completely impossible for you to get a straight answer from anyone, simply because the answer does not exist. Nobody has a crystal ball, nobody knows what will happen in a month and a half.
