Am I within the 72-hour deadline for my Fit to Fly test before flying to Bangkok?

The user is inquiring whether they will meet the 72-hour deadline for their 'Fit to Fly' test before departing for Bangkok. They plan to take the test on Wednesday, receive results on Thursday evening, collect the certificate on Friday, and fly out Saturday, arriving in Bangkok on Sunday. Comments clarify that the 72-hour period is calculated from the time of the flight departure, not arrival, and that they should be within the limits based on their test schedule.
