The verification of China Eastern Airlines' travel itinerary shows falsehood.

The verification of China Eastern Airlines' travel itinerary is not true, which may be due to the following reasons:

1. The printer cartridge is out of date or damaged, which makes the printed travel information unrecognizable.

2. When printing the itinerary, it was not connected to the air mail system, so it was impossible to verify the information.

3. Other unknown printing or verification problems.

To avoid this situation, you can try the following methods:

1. Make sure the printer works normally and replace the ink cartridge in time.

2. Contact the customer service of China Eastern Airlines to ensure that the travel itinerary is connected with the airline letter system.

3. If the problem still exists, it is suggested to complain to relevant departments and seek solutions.
