> This would be fine, except that airlines have already sold an avereage of 101,500 tickets per day and seats are still on sale.

My understanding is that based on existing sales alone, there are already 101,500 passengers/day. And in order to get 100,000, they have asked airlines to not sell any more tickets at all.

If you imagine that airlines were previously planning to sell a further 20,000 tickets per day, and they cut that down to 0-100 per day, that's a huge drop that is sure to impact anyone looking to buy tickets at this time.
