On the weekend ahead of Independence Day, there was an aviation chaos at every American airport.
On Friday alone, 500 flights a day were canceled and 7,800 flights were delayed.
Thousands of flights were canceled and delayed on Saturday, forcing some passengers to stay up all night at the airport.

I don't know how to get home.]
The difficulties are spreading as the airline union strikes for better working conditions.
Delta Air Lines pilots protested ahead of a strike at major airports in the United States demanding better treatment, and in France, Charles de Gaulle Airport employees went on strike on the 30th of last month.
[Fabry Krike / Secretary General of Airport Union: During the Corona period, we reduced thousands of employees, but the number of passengers increased again.
There is a serious shortage of manpower, but there is no increase in wages.
It is said that the wages will be raised much less than the reduced wages during the corona virus.]
Following a strike last week by flight attendant unions in Belgium, Spain, Portugal and Italy, workers of low-cost airlines EasyJet and Ryanair went on strike this weekend.
The number of passengers has increased again, but the airline industry is having a hard time responding as employees are increasingly dissatisfied with high oil prices and a shortage of manpower.
