Hello. I just joined flyertalk and not familiar with this forum. I'm not sure whether I can ask questions here or not, but since I'm in an urgent situation, I'm posting here. If I'm posting in a wrong place, please let me know.

I'm now staying in La Paz, Bolivia and plan to go to Brazil, looking for the cheapest flight form La Paz or Santa Cruz, Bolivia to Rio de Janeiro, Brazil.

Actually I found one from Santa Cruz (VVI) to Rio de Janeiro (GIG), it's GOL. It's 2,222.31 Bs., which is approximately US$317.47.

This is affordable price for me, but the problem is schedule.
The plane departs on July 12 and July 16.
But I must arrive at Rio de Janeiro on July 15.
July 14 is ok but July 12 is too early for me.

Is there any alternatives?
The only cheap airline I know is GOL. Please tell me any other cheap flight carriers from Bolivia to Brazil. I need it on July 15 or July 14.

Of course the cheaper, the better. I can afford around US$300.
Thanks in advance!!
