I hadnt flown for like 10 years and never alone until 2017 when i went Perth, then i got sick and homesick too. My trips last year were fine. The only issue i had was i couldnt sleep on my trip to thailand from Sydney and back, it was a 9 flight time
Its hard when my seat was surrounded by the same group of people on the way to thailand. My flight back home was okay, I was just uncomfortable in the seat.
