Can't buy flight tickets online- lan, starperu, aerocondo

Hate to bother everyone with a technical computer problem, but I have been trying to get into www.lan.com.pe, but I click my country of origin(US/Canada) and all the site does is refresh. I went on lan.com, but the flight from Lima to Arequipa is way too expensive. Does anybody know what I can do or what I'm doing wrong?
I also tried to find a flight on starperu.com, but wasn't able to enter the departure or destination.
These 2 sites seem to not be operating correctly, but I need to buy a cheap round trip ticket. I called starperu, but the ticket is $129 and I've read that there are some tickets for $80.
Is $129 cheap or not?
Aerocondor.com.pe works fine, but I have to enter my passport number in order to find out prices, which I am not to keen on doing. Has anybody entered their passport # and not bought the ticket?
I'll be looking on more sites and keep everybody posted on what I find and if my techinal problems change. Thanks!

Try Aerocondor.com they have fewer flights than LAN, but are a bit cheaper.

Hi eissert,
If you delete your internet cookies and then go to lan.com it will ask you again your country of origin and then you can select Peru. I don't know why but prices on lan.com through the peru website are many times cheaper.

Good luck

I flew from Lima to Arequipa on Star Peru for $52 yesterday.

I booked it at the desk of my hostel. Are you in Peru now? A travel agency might be able to help you. Otherwise, it doesn't seem like you need to book that far in advance. I booked my ticket the day before I left.

No, I'm not in Peru right now. I am traveling there on June 30th or around that time. I'm going to a language school so I have to be there by Monday (july 2) morning. I want a flight, at least one way to Arequipa, so I can get to my school with assurance that I'll be able to get there. I also need to tell my host family about my arrival time. I don't have as much flexibility as other travelers and this is my first time going abroad alone, so I just want a little extra security, i.e. having transportation already set-up , for myself.

$52 is great, that's $2 more than a VIP bus ride with cruzdelsur.
