Cost of round trip, coach-class ticket
"HOw much does a round trip, coach-class air ticket cost from my nearest international airport to Peru?"
There are a number of factors that affect the price you will pay. The first and main factor is the dates involved. During certain seasons, tickets are much higher (Christmas vacation, for example). Then again, during slow or very competitive times, tickets can be cheap.
The best way to get a good price is to start as soon as possible checking airline prices to get a feel. If you can be flexible a couple of days on each end of your planned trip, it could mean a big savings.
Generally, though, a ticket will cost around $750.00 to $1,300 US dollars. The last time we flew into Lima from San Francisco, though, we got a great price of about $470.00 round trip.
Do a thorough search with some reputable ticket sites. I have had good success with OneTravel but it doesn't necessarily have the best prices always.
