Here is what I know so far. My friends were supposed to travel to Cebu via Hong Kong on Cathay Pacific. I saw on Philippines CNN that flights were no longer being allowed from Hong Kong. I contacted my friends, and they were able to confirm this and get full refunds. They are now routed to Manila through Singapore.
My husband and I are flying Delta through Narita to Manila, which is fine. However, several months ago Delta rerouted our return home in April to their new service via Incheon. We have been carefully monitoring the news. 2 days ago when Delta issued a caution that some flights through Incheon may be affected, I called them twice and Delta could not find an alternate path out even if I purchased my own inexpensive tickets to Singapore. Then last night my husband found a new Delta news release at this site:
https://news.delta.com/delta-reduces...id-19-outbreak. In the middle of this announcement, it says, "
The airline’s new service from Incheon to Manila, previously scheduled to begin March 29, will now start on May 1. Full schedule details will be available on delta.com beginning Feb. 29."
I called late last night to beat the rush, and Delta rebooked us on a PAL flight from Manila to Haneda in Tokyo. In Haneda, we will continue our trip home on a Delta flight. They gave me the usual warning that this is the way things are now - but they don't know what the future will bring.
I hope this info will help someone else.
