What should I enter for flight number and intended date of arrival on the Thailand eVisa application if I haven't booked my flight yet?

When applying for the eVisa to Thailand, if you haven't booked your flight yet, you can estimate your flight information. One user mentioned that they selected a hotel and looked for flights on Google for their intended arrival day. Another highlighted that they provided a flight ticket after the visa was granted, which indicates that while booking is not necessary upfront, having an intended travel plan is helpful.
