Give your dates, and will check. Lan does not have local or foreigner rates. You pay what the website says, although local promotions can exist and be cheaper.
My only affiliation is with Liquid Force and Caution. My company is the first distributor of kitesurfing in Ecuador, which I started doing in 1999. In fact I introduced the first Wipika kites oi Mancora back in 2001 with Wawa Paraud, who is one of Peru's awesome surfers. David is a welcomed new comer to the market.
I just tried again, using the Peruvian site as before, and got a round trip ticket to Piura for 78.54 USD traveling on Oct 14 and returning on the 28. The rates have changed 3 times already. If you cannot find the prices, email me the dates, and will work that on my end to get a reservation number.
Another person to try is Ruben Palamino, he's a straight-up Cuzco based travel agent, but he was super helpful and help us find must cheaper flights to and from Tumbes/Piura and Cuzco when we went a few years ago.
Ended up getting flight to/from Piura as more options to choose from. Didn't really want to hang in Lima as want as much time as possible for surf/kite waves on north coast... Interested in what jose has to show us in/around Paracas area and have the expertise of Skip while in the mancora/the north.
Tumbes is supposed to be more scenic beach route while piura goes through desert so we shall see. A friend did the GYE route and got picked up by Skip (group of five) so will be comparing routes/ease/hassle and giving personal expeerience of pros/cons of each. We shall see if we get screwed on the ticket. i hope not as I will for sure write that up too
This is an interesting post, as I've been looking for a lot of the same answers recently as well!
We're heading to Mancora in just a couple of weeks, and will be traveling down from Guayaquil. I've done a ton of research into this, but its still really hard to figure out when (and which buses) leave. I do know there are two main companies that do this route: CIFA and Ormeño.... Orrmeno is supposedly the best and safest, but one source tells me it only goes 2x a week, another (a hotel owner) tells me it leaves at 11:30am daily. I hear its more expensive, but that's a minor concern.
There are local buses as well, but have read to avoid them at all costs.
I also know its possible to take a taxi (for around $150, but this can be even more risky than the bus) and have even bigger issues crossing the border.
We'll be doing this route with our kite gear, so wish us luck.. we are well traveled, but I still expect this to be a big challenge... if anybody has more solid information on this, let us know. I know one poster suggested to take the night bus, but I've also read that's also not recommended.
