Isn’t that pretty common? If I know I have to get up unusually early I can never sleep. If I have to rise at 4AM to drive to a bicycling event that starts at 6 I can never sleep before that. Same for very early flight departures or anything out of routine. I’ve adjusted by just getting up so early every day that there’s no possibility of anything being extra-early!
I found that if I set two independent alarms (i.e. my phone and my alarm clock), I sleep much more soundly when I need to get up early -- the second alarm gives me reassurance that I won't oversleep even if my phone battery dies so I sleep better
I don't think so. I travel regularly to Sydney for work, the flight we catch to get a full working day has a check-in at 5am. None of my colleagues who I travel with have this problem.
I try and deal with it by avoiding early flights if possible and flying the day before and staying the night but it's not always convenient with schedules, etc.
