The American airline Southwest announced Thursday to once again postpone the flights planned on the Boeing 737 MAX, until June 6, due to the uncertainties still surrounding the return to service of this plane.

The group joins American Airlines and United Airlines, which have both removed the 737 MAX from their flight programs until June 4.

"By taking the lead, we can reduce and avoid last minute flight cancellations and avoid disrupting our customers' travel plans," said Southwest, the 737 MAX's largest customer with 34 aircraft.

The postponement affects around 330 flights a day, or 8% of the daily flight schedule, says Southwest, which promises to transfer affected passengers to other flights.

"We apologize to the passengers affected by these changes and thank them for their patience," concludes the airline.

The 737 MAX has been banned from flying worldwide since March 13 following two accidents that killed 346 people.

Southwest, like American Airlines and United, has already postponed several times the date on which it thought it could reintegrate the aircraft into its flight program, and hoped the latest news could be able to reuse the 737 MAX of its fleet from April 14.
