Oh boy... there was a time the company posted here on TalkFreelance. Not sure if it still ran by the same owner:

I travel a lot, so I contacted them out of interest on how they are able to get tickets this cheap. If this turned out to be legitimate, this would have meant thousands in savings every year.

The original site was http://www.flightsprite.com/ , then it went to strawburries.com then, I guess, limeflights.com is coming up.

After multiple back-and-forths, what caught my attention is that while they offer $500 flights for $130-150 (hard to fall, isn't it?), they say they "are actually selling non-refundable bookings that no longer needed by their original buyers and they wish to sell them through us at a very cheap price. We get our commission from these ticket holders themselves". From basic knowledge you know that it costs up to $250 per person to correct the name on a flight ticket, because tickets are issued in buyer's name. I have no clue how to walk around those charges. But what is fascinating is that while they say they are limited to certain airlines, they were able to provide rock bottom pricing on different, completely random flights, which begs the question - how are they able to find these fliers who want to sell their tickets this fast? They don't.

Now, I cannot attest to that Ahson Rafiq (a.k.a Gurilla here on TF) is still somehow related to Strawburries or not, but none of his websites work now, including his personal design site gurilla.net. I reject to think that someone with a design talent would get involved in scam schemes like these.
