Is there any website that offers more air ticket permutations than the standard airline sites and pages like Expedia, Orbitz, etc?
When shopping for tickets I have found different websites that are good at different kinds of searches but never one site that will search any way that I want it to.
As an example, let’s consider a current search I would like to try. Let’s say I am in NYC and I have a 4 month window to travel, I wish to visit 2 different cities (let’s say Paris and London) and I’m flexible about how long I’d like to spend in each (say, between 1 and 4 weeks), the order that I want to visit them, and the dates that I depart and return. IOW, I have a lot of leeway to change my schedule/plans in order to get the lowest airfare.
I fly on Northwest/KLM a lot and frequently use their website. It’s pretty good. For example, I can search for a roundtrip ticket 3 days in either direction of the dates that I enter–the prices are displayed on a 7 x 7 (I think) grid offering a lot of choices. But, this feature does not work if I have multi-city/open-jaw flights or have flights that originate outside of the US or Canada. And, I can’t check prices for NYC to London to Paris to NYC and have it ALSO check for NYC to Paris to London to NYC.
Of course I could check every possible combination with separate searches but there are thousands–if not more–permutations. I think that this is the same reason that ticket companies/airlines don’t offer such flexible searches–because it would take too much time and computational power to do so–but surely there is some way that I can let my good ol’ computer automatically perform all these different searches for me.
Any help? Has anybody written a meta-airline-ticket-search thingie that I can use? Is there already a website that does this?
Thank you.
