MANILA - Philippine Airlines on Wednesday announced what it said was its biggest seat sale this year to mark its 78th anniversary.

One-way base fares start at P78 for domestic flights and $78 for international destinations, the flag carrier said.

Over 2 million discounted domestic and international seats will be available starting March 1 to March 10, said PAL vice president for sales Ryan Uy. Travel dates are from March 16 to Dec. 31, 2019.

The airline's "next generation" computer system upgrade next month will offer passengers a " no-crash" booking experience, even with high traffic during seat sale events, Uy said.

PAL said the promo fares are applicable to over 30 domestic and 40 international destinations.

Tha airline recently announced non-stop flights to Hanoi, Phnom Penh and New Delhi. It also welcomed its 5th Airbus A350-900 earlier this month.
