Even though those might be difficulties it doesn't mean you should fuck over customers instead of overcoming them.

> Dozens of flights were canceled and some were diverted to other airports. An Air New Zealand flight was forced to return to Auckland after flying two-thirds of the way across the Pacific Ocean, resulting in a 16-hour trip that ended where it began.

Yeah at the airport if you're flying internationally CBP takes pictures at the gate. Deletes after 15 hrs iirc for US Citizens.
