Seen some of these mentioned around here and so I started looking at cheapoair.com and it has, when you Google it, the most horrible reviews you can find. So, in continuing searching I find these 2 other site and the flights, costs, layout of the search engine and types of graphics were so similar, I started doing some betterwhois domain name snooping and pretty much confirmed these 3 are related. I sent an email to insanelycheapflights.com and they actually responded that they are "sister" sites to cheapoair.com.

Anyway... cheapoair.com's reviews are just so bad and so consistently bad, would we agree the other 2 cannot be trusted? You can find some so so comments about onetravel.com, but not much about insanelycheapflights.com - and they said "We are sister's company however, suggest you to experience our best services in order to have your own perception for our company", but I am super leery given the price of the tickets I need, their importance, and the fact they admit being related so not sure how they wouldn't have the same reported issues and tactics.

The 1 thing is, their prices - all 3 sites - are the same and consistently lower than anything else and even a few consolidators I have contacted that I have read about here.

thoughts?
