I need advice on when the cheapest time, month/day to travel to Gunagzhou would be. I had bought ticket for 973.00 usd to go from PHX to CAN April 5th to the 16th. Got to LA and had to CX the remaining flight, (emergency). Now need to rebook, (marriage can't wait) and prices are 2x what I paid. So does anyone know when to travel cheap?
