Just got a message from Cheapoair telling me the airline made changes to my 4/21/20 flight from Manila to JFK (NYC). Had to have Philippine Airlines tell me by reading a message on their web page that as of 4/6/20 All April international flights are cancelled. They will start again in May, but no flights will be scheduled to JFK until June. They told me I will have a credit with them which I have 12 months to use.
If it were the USA and they cancelled the flight I would get a refund. Korean Air is still flying Manila to Seoul, South Korea, with a 5 hour layover and then 14 hours to JFK. Sure not using Cheapoair, Expedia or any other such flight planner as they are impossible to deal with if anything changes. Later today gonna start dealing with Korean Air, see what I can find out.
