Can I change my flight for the Thailand Pass without needing a new pass?

The user inquired about changing their flight to an earlier date while using their existing Thailand Pass, seeking confirmation that the pass remains valid. They found out that the Thai Embassy permits flight changes within a 72-hour window. Respondents shared their experiences: one confirmed that having multiple Thaipass QR codes did not lead to issues at entry despite the change, while another recounted difficulties faced at the airport due to not having the updated hotel certificate after a flight change.
