I am in a similar situation. Although the travel ban is in place till 14 April ( In India), there is a probability that it might get extended. I too have lost money in flight cancellation and the refund from airbnb is taking time . The flight prices are very high. My visa expires on 18 April. I am feeling very hesitant to book anything now as the Indian government can extend the ban if it feels like it.
On one hand , I don’t want to be in a situation where I need to justify why I didn’t go , as the same would amount to giving the visa officer the discretion to cancel my application. On the other hand , I ve already faced two flight cancellations and two bnb cancellation. So , I just don’t want to lose more money .
