Is there a site/app out there that'll let me sign up for alerts for airfare deals to Japan?
Be careful with Google flights so you don't end up on one that has a layover in China.
At least, that's what I use. You can just set up a few dates and it'll give you alerts when prices change.
May is fine depending on what part of May. Are you thinking early or late May?
I was going to make a new thread, but I was lucky enough to find a megathread already for this kind of inquiry.
My friends and I are planning our very first international trip to Japan in May 2018. I hope that's a decent time. A cursory look at the thread tells me the months of November/December are preferred, but I think our schedules have settled on May. Being my first international flight, I have no idea where to start, but the OP is giving me useful advice. Is there anything you guys can offer in general? Suggestions on where to go and such? I'm starting from zero so anything will be useful. Thanks!
