5. Set date: Confirm that the date input box has been set correctly
6. Execute query: press → Enter(preferred option) or click the search button

Key operational points

Departure/destination input

• First usetypeEnter the city name in the input box (such as "Beijing", "Shanghai", "Guangzhou", "Chengdu", etc.)
• The system will automatically display a dropdown selection list
• UsesearchFind the specific airport option (such as "Beijing (Daxing International Airport)(PKX)", "Chengdu (Shuangliu International Airport)(CTU)", etc.)
• UseclickSelect the target airport
• Multi-city versatility: The skill has been verified to support any combination of Chinese city names, including first-, second-, and third-tier cities

Query execution strategy

• Preferred option: Usepress + EnterSubmit the form (avoiding overlay blocking issues, verified as effective in multi-city scenarios)
• Alternative option: If the Enter key is ineffective, usesearchFind the search button andclick

Error handling mechanism

• Element invisible: Try using keyboard operations instead of mouse clicks (keyboard operations performed more stably in multi-city testing)
• Page structure changes: After each interaction, re-usebackboneorsearchGet latest element reference
• Input failed: Retry input or use an alternative city name format
• Dynamic element reference invalid: This issue was found to be common in multi-city tests; it is recommended to relocate the element before each operation
