Can I use a different flight number for my Thai visa application and the Thai Pass?

When applying for a 60-day visa to Thailand, it's acceptable to provide a tentative flight number that may differ from your actual travel itinerary. Many applicants have confirmed that a quoted itinerary is sufficient for the visa application as it mainly helps the authorities understand your intended travel timeframe. However, it's noted that the flight information may be more critical for the Thai Pass, so it's advisable to check the specific requirements for that application.
