MANILA - Philippine Airlines on Tuesday warned the public against a fake $1 promo fare that is being circulated on social media.

The website www.philippineairlines.com-cheapflights.today dupes internet users into answering a survey, which may compromise their data, the airline said in a statement.

"The public must not fall prey to bogus ads such as these. False advertising will not be tolerated," it said.
