I know Southwest "ding" is pretty cool, but what are some other programs or newsletters that monitor super-cheap flights… even to other countries

I'm in Denver, CO, and I'm constantly looking for rediculously cheap deals just to get out.

Some places in particular that interest me are, australia, japan, china (hong kong), south america, europe… hmm, I guess I'm covering a lot of ground here, no?

sign up for Travelzoo and Shermans Travel – They will send you offers for all kinds of different travel options but pick thru and you'll find some good deals! Just booked my last flights thru one of them.
