Almost all intl departures out of iad were delayed by 2-3 hours today due to lack of cleaning crews to clean the planes. I am on iad-muc which just boarded 3 hours late. Rumor is there were a large number of employees who called in sick due to a labor dispute

Plane was delayed in 20 30 min increments, which is always miserable for passengers

Hope this doesnt become the norm for iad
