This has to stop. Our government needs to put an end to this. The laws need to be enforced and strengthened.

Every available employee should either be at the airport or call center rebooking with whatever option the passenger deems is best for them, with individual employees facing personal fines if they refuse to re-accommodate on the available flight.

Change the law so that strikes/lockouts that inconvenience the public are not allowed. Works in many countries. I would even go further and allow passengers to sue employees and their unions ( or managers and the airline in the case of a lockout).
