LE BOURGET, France (AFP) - Boeing said on Wednesday that US plane leasing firm CIT had ordered 30 of its new, medium-haul 737 MAX aircraft in a deal worth US$3 billion (S$3.8 billion) at catalogue prices.

The announcement comes on top of an already solid order book at the Paris Air Show for the US aviation giant, which has also announced the launch of a long version of its next-generation Dreamliner 787.
