Would you feel comfortable with this?

3. Jetstar Asia BKK-SIN T1 0920-1255 (flying T1 until terminal change 25/03/2023). I can book this classic reward, but I only get 20kg baggage. Kinda sucks though because I'll need to be up early and then sit on an overnight flight, and I'll arrive at Singapore before the lounge opens sometime around 2 or 4pm.

Check if there is now a later flight?

Thanks for the tip! Major kudos! But the flights aren't yet avaialble for booking. I wonder when we'll see a schedule.

Edit: I also wonder if the new flights will operate from T1 until the 25th of March like the rest.

According to the article:
All Jetstar Asia (3K) services will continue to operate out of Terminal 1 in Singapore's Changi Airport until March 2023.
