I think it's more of an issue of how fast the world economy and travel industry will recover and how soon people will restart traveling. TK will still be around but will demand pick up quickly?
My gutfeel is that none of the aviation markets (including that of Turkey's) will recover even after the Covid-19 will totally fade away. Personally I don't think it will totally fade away with the approaching summer!
The low cost market and charter carriers may start recovering much earlier but the legacy carriers will continue to suffer. Wealthy air travelers (particularly the C and PE class pax from the business world) will learn further as how to survive in their business while sitting at home/office but still carry on their daily biz (tele conferencing, etc. etc.) to stay "healthy", during this period of 1-2 months when flights are being banned! Backpack travelers who could afford tickets for legacy carriers (making use of promotional fares, etc.) may not have such budgets available for them.
While pax numbers decrease, duty sales volumes will also decline at the airports. A lot of airline staff will loose their jobs; there already are serious examples in practice. Tourism industry will greatly suffer, bcz. tours will sell less and it may not help to give rock bottom prices. A good percentage of these touring travelers will still want to stay at home in the fear that another epidemic may soon start. Countries with rich touristic regions, sightseeings, etc. will receive much less than what they were used to have: possibly half of the hotels, resorts will be left empty! So it will be kind of avalanche effect.
In short, the New World will be much less offering for everyone than the Old One!
