Thank you, Mr. Chair.
Before answering that, I also want to acknowledge the workforce of all of the airlines in the country. They have done exceptional work in the most incredibly difficult circumstances. I just want to thank you for acknowledging that.
I can't speak to the particulars of any specific incident. What I can say is that weather delays, of course, have a safety element related to them, but ultimately those decisions are up to the pilots and to the individual airlines.
As I said in my opening statement, the cancellation of a flight is the last resort. It is only used if the pilots and decision-makers are feeling that there is a safety concern. In no way, shape or form do they do it lightly.
