Hi,
I had purchased a flight from LAX-CAN with a transit at Narita Airport by ANA but I just realized that the transit would only be a little over 30 minutes and I'm travelling alone with my 2 years old son. We'll be changing planes and no terminal changing.

The last time I went thru NRT was over 4 years ago and I remembered it involved some running. Now is this suicide? What's gonna happen to us if we miss our connecting flight to Guangzhou? Just found out that's the last flight for the day too. Ouchy!

Plz plz help.
Thanks!
