I thought this fare was gone. I had been trying to book tickets for my aunt these past few days but could not get it to work and now all of a sudden they're back. This is an incredible fare. For those who want e-tickets, make sure to check zuji.com as well.
I just purchased a weekend trip from PDX with stop in SFO and NRT and I'll probably spend a day in Makati area (Peninsula and Shangri-la rates are quite reasonable) and that should be quite a good weekend while earning miles on UA and probably miles to AA for the JAL segment.
Manila is indeed chaotic, but it also can be a lot of fun.
