Mubasher: US-headquartered Southwest Airlines has announced that it will extend cancellations of Boeing 737 MAX flights until 6 June 2020, Reuters reported on Thursday.

Southwest’s decision will remove around 330 weekday flights from its total schedule of more than 4,000 daily flights.

Airlines that own 737 MAX are cancelling over 10,000 flights per month after the aircraft was grounded following two fatal crashes that killed 346 people.

The Federal Aviation Administration (FAA) said that it may not approve the return of the MAX until March or later.

Earlier in January, the FAA proposed a $5.4-million fine against Boeing for faulty wing parts on 737 Max aircraft.
