This question already has an answer here:

I'm looking for extremely flexible flight search engines. Here are the features I'd like to be able to utilize:

  • More flexible date search, specifically, I want to be gone between 7 and 12 days, but I'm good with leaving and arriving any time within two months. I can search on a site like kayak, but only within a few days, and it won't preserve my trip length.
  • "Super long" layovers, rather than 3-8 hours in a layover, I'd like a longer layover, more like 16-48 hours. Sometimes these pop up in the searches, but I can't figure out how to locate them specifically.

Is there any site that works well and has more options than a site like kayak? For what it is worth, I'm looking to travel from DSM to RIO in September or October of this year.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

The higher search flexibility comes at the cost of maximizing your chances to find the best price. I've noticed on Kayak that if I do a range search, I sometimes don't find the lowest price as I would if I did searched on specific days. – karancan Jun 18 '14 at 0:48
This question was marked as a duplicate, yet the linked question does not actually answer what I am asking for. The link refers to searching with a range of a few days on either end, not weeks, and does nothing with allowing for searching for long layovers. – lfrandom Jun 18 '14 at 13:30

Have you tried If it doesn't have the features you require, we'd be interested to hear from you.

In addition to Kayak, there's also Google Flights at
