It’s just Scott’s Cheap Flights with a rebrand? It wasn’t that great ~10 years ago… Back in those days I used airfare watch dog pretty often.
It doesn’t really matter where you get fare notifications… You just need to watch the prices often enough to know what a normal price is so you can recognize a good price when it comes around.
Way back when I was finding round trip flights from NYC to Tokyo, Hanoi, etc… I wouldn’t pay more than $400 round trip. These days I’m only travelling to see friends or family so I don’t track it as closely.
Don’t know about the UK but I’ve been doing this for ~8 years… I make an American salary and live in places that have a MUCH lower cost of living.
It’s been my experience that my colleagues never care. However, HR is a nightmare to deal with. It’s literally their job to find out how to pay employees less. Every time HR has found out what I’m doing it’s been a problem. This is the main thing I have to be aware of when interviewing for new positions… I keep my mouth shut until after onboarding is finished and I never have to talk to them again.
On the tax front, the Americans have an exemption you qualify for if you are out of the country for 330 days or more per year… Basically the first $120k of your income is not taxed and anything you make above that amount begins to be taxed at the lowest tax rate. I don’t have to mention this to the employer at all because it’s part of the paperwork I file with the government at tax time… It has nothing to do with the job really… My tax rate has been 1% or less for nearly a decade now.
You should talk to a tax strategist. They may be expensive up front but they will save you MUCH more than whatever they charge in the long run.
EDIT: If someone knows a good place for finding contract work, I’m looking for SRE gigs.
