Ryanair expects Boeing to produce 38 of its 737 MAX planes per month by the end of the summer and possibly up to 42 by October, subject to U.S. Federal Aviation Administration approval, Ryanair CEO Michael O'Leary said on Monday.

Indian low-cost airline SpiceJet is to restore its grounded Boeing 737 MAX fleet to service after signing a crucial engine maintenance deal.

Boeing aims this year to hike 737 production to at least 38 jets monthly, and possibly as high as 42 if it receives permission to do so from the Federal Aviation Administration.

President Donald Trump's nominee to head the U.S. Transportation Department said he will keep in place a cap on production of Boeing 737 MAX planes put in place after a mid-air panel blowout last year until he is satisfied it can be safely raised.

Boeing is seeking temporary regulatory exemptions for a stall-management yaw damper (SMYD) system on the 737 Max 7 and Max 10, saying a classification change left it unable to demonstrate that the systems meet airworthiness standards.

The B737 MAX model forms the bulwark of SpiceJet’s plans for revival, which includes sorting out litigations against it, paying up where needed and getting fuel-efficient aircraft like the B737 MAX which will help it fly longer distances to high-demand destinations like Riyadh and Jeddah without any operational restrictions.

SpiceJet on January 28 announced that it is set to re-induct its first ungrounded Boeing 737 MAX aircraft into operations from January 29. The shares of the company rallied nearly 3 percent after the announcement. (This is a developing story. Come back later for more updates)

Domestic budget carrier SpiceJet on Tuesday said it is set to re-induct one of its grounded Boeing 737 Max aircraft into operations from January 29, as part of its plan to put all these planes back into service in a phased manner.

As part of its broader fleet restoration plan, SpiceJet intends to bring ten aircraft back into service by mid-April 2025. This includes four Boeing 737 MAX planes, with the newly re-inducted aircraft being the first of the batch. The airline is poised to gradually reintroduce more aircraft as part of its strategic push to enhance its fleet.

Lufthansa Group is overhauling low-cost carrier Eurowings with 40 Boeing 737 Max jets, marking a significant shift from its all-Airbus fleet.

Ryanair ( RYAAY) ( OTCPK:RYAOF) Chief Executive Michael O’Leary estimates that plane maker Boeing ( NYSE: BA) will be able to lift output of its 737 Max jetliners to 38 a month by the end of summer and possibly to 42 by October if aviation authorities approve, Reuters reported Monday.
