Question : In the next four weeks, what day should you book your trip?
Answer : Since low prices are preferred, look at Mar 2nd. As of Feb 20th, it's showing the cheapest ticket sales at $3,576. That is 4% below the average price for this route, so you can spend that extra cash on an adventure rather than the flight.
Question : Is the price you found a good deal?
Answer : Flight prices change a lot less than most routes from the Russian Federation for AER to PHX. They range from $3,545 to $3,889. The further out you book a route, the more likely you are to save.
Question : How long do most people visit Phoenix?
Answer : Of course you're not most people, but if you were, you'd stay roughly eight days.
Question : Is price more important than specific travel days for you?
Answer : The best day to fly on a budget this month is Thursday. Being flexible with your travel days garners even more savings during booking.
