Thank you everyone for all your replies. My first plane in the US was on June 24th so forgive me if I didn’t reply to everyone promptly as I was trying to pack and get my ducks in a row before my flight. So this is what happened:
1) Flight from Austin to DFW and Flight from DFW to LAX —> No vacant seats. Flight was pretty full but at least everyone was wearing a mask. American Airlines states that if you don’t wear a mask on board then you may not be able to fly with them anymore. So, everyone was being really abiding and didn’t attempt to talk to anyone or congregate in the aisles. When I checked in at Austin, I could not get a boarding pass to HK because of the restrictions and no HKID. I was told to go to the Cathay counter at LAX to get our boarding passes. Austin did ask me for documentation before giving me ANY boarding passes.
2) Flight from LAX to HK —> Cathay counter at LAX took my documentation and sent an email to HK immigration. Luckily I was at the counter about 1.25 hours prior to departure. I believe June 25th was a HK holiday because they didn’t receive any email from immigration. Then 25 minutes prior to last boarding before they close the door, Cathay called HK Immigration and finally got a call back 5 minutes before they shut the door. OMFG! I was thinking I’m going to have to stay overnight at an LAX airport hotel or just fly back to Austin because this may not be happening. I showed them my email from immigration but they told me that it didn’t have my name on it and was just a generic email. They needed an official document from Immigration showing my name or they had to confirm with them over the phone. 5 minutes before the pilot threatened to shut the door, HK Immigration finally called to confirm. Yay!
Flight was 1/3 full approximately. Flight was fine.
3) Stopped at Passport Control/Immigration. Had to go to supervisor’s office to show him documentation.
4) AWE was cold as hell. Saw about 3 or 4 camping tents there, which was pretty smart if you have kids. Sandwiches and a tall bottle of water if you ask for it. Landed in HK at 6am and left at 2.30pm. Got into Uber and driver immediately asked me where I flew in from. He probably thought I flew in from Malaysia or Thailand but when I told him From the US, he almost panicked. I don’t blame him.
Lots of stories from this trip but it was fine.
