M0hamed, that was a terrible drug choice. Firstly, alprazolam is a Schedule IV controlled drug in the USA, and it's insane to transport it to the USA even with a prescription.
Secondly, it's a very short-acting benzo. You're likely to get brief but very deep sleep, and are a very high risk for a DVT.
Returning to the original question, Jetstar Business is well worth buying at the outset with a Max pack to get Business level Qantas earning and status.
Recline is like domestic First Class in the USA, but the seat is much narrower.
The best options for Business Class to Honolulu from Australia are Air NZ (one-stop but the only flat-bed) or Hawaiian (similar seat to JQ, but far superior catering and connections).
You seem to dislike a lot of my posts of late. I didn't think this was WebMD or DFAT nor did I seek your advice.
