Great for hotels, less for flights

I have used Hipmunk for at least two years now and have used it to book several hotels in Barcelona, San Diego, London and Miami.
Ive also searched for flights using this tool but for that, I have found some other search engines have been somewhat better especially when looking for multiple-leg and open jaw flights.
I do very much like the agony sort functions.

Medelegant about Hipmunk Travel Search, v3.2.4
