LONDON, Jan 29 (Reuters) - Ryanair is confident

that Boeing ( BA ) will ramp up its production of 737 MAX jets

to 38 per month this summer and that it will be allowed by the

administration of U.S. President Donald Trump to then increase

that to 42, its CEO said on Wednesday.

Michael O'Leary, whose airline is one of the largest

customers of the 737 MAX, was speaking in London following

meetings with Boeing ( BA ) management in Seattle in recent weeks and

ahead of a visit by Boeing ( BA ) CEO Kelly Ortberg to Ryanair Dublin

in February.
