The work stoppage, which took effect early Friday, is expected to affect up to 30,000 passengers. Officials with Aeromexico say they are working to put their passengers on other airline’s flights to avoid delays.
But the strike has already triggered long lines and confusion at Benito Juarez International Airport in Mexico City. The 1,500 stricking flight attendants are demanding a pay raise of at least 15 percent. Aeromexieo says it is only willing to give a raise of 8.5 percent.

How many passengers will be affected by the strike？
