KEY POINTS
  • Airlines are making unprecedented cuts to capacity and scrambling to find other places to save cash.
  • The coronavirus and related travel restrictions have led to a collapse in air travel demand.

But several airline executives told CNBC they are considering all possibilities. The executives cautioned that such a ban was not imminent.
