Is Google Flights useful for calculating?
Some suggest Expedia, some Kayak and maybe some CheapOAir.
For airline services, Delta, America Airlines and SkyBlue are recommended for ones in Japan to travel to America in. Japan Airlines I heard is good while cheaper ones are worse when traveling to Japan.
My mother recommends Chattanooga over Atlanta airport due to Chattanooga's being much less security before going on or off board. But my local teacher and her husband recommend Atlanta, though it's further and has traffic so rough, not even longtime drivers can handle it well while it is said to best go to a far bus or train stop to access Atlanta airport.
And what weekday and month is usually best?
