My first flight in 7 weeks.

[Terpe]

....nervous on my own with the flights and no one to watch my gear if i go to the loo!

I have one of those 'manbags', just big enough to carry passport/tickets/wallett/cash/coins/documents etc. just keep it on your body.
Any other carry-on luggage is locked and placed in the overhead locker. Nothing much else you can do.
In over 30 years of regular business travel (and with all the business electronics etc) I never had any problems even once.
