I'm pretty sure Scott's Cheap Flights[1] makes a good deal more. It's going to be hard to have a big enough audience if you limit yourself to only one city.
Money from this is dwarfed by my day job income so I’d be happy with $1,000 per month
You'd think that this is the kind of thing which would be insanely easy to automate.
Absolutely horrible website btw. now I am trying to close account, when I tap on profile it asks me for airport and can't do anything without filling airport and then after filling it I find out there is no automated way to close account when you check the options.
I guess the moral of the story is, simple email updates don't pay (enough).
