Where to get cheap airline tickets online?

[StevenYoo]

Hello all,
My friend needs to go from NYC to Denmark. Where are good places, online and off, to get good prices on airline tickets, both round trip and one-way?

Thanks for all your suggestions.

My co-worker just told me the other day he got some really good prices for tickets from Orbits.com ... Check it out, its not like Priceline.com or Travelocity.com where you might get screwed over with the itinerary ... You know before you buy the ticket exactly what date and time you'll be leaving and coming back.

i bought mine from Orbitz.com. do not use travelocity...they screwed me. you also have priceline, or hotwire.com but you never know with those. orbitz is your best bet i think
