LONDON, Aug 27 (Reuters) - Ryanair expects to

see a "reasonable spike" in capacity in late December and early

January after Boeing ( BA ) agreed to bring forward the delivery

dates of some 737 MAX aircraft, CEO Michael O'Leary said on

Wednesday.

The delivery of 25 aircraft by October was in part motivated

by the risk of future tariffs on jet deliveries, O'Leary told a

news conference in London.
