Boeing Co. grabbed an early lead in orders and commitments at the Paris Air Show over Airbus Group SE, piling up a haul valued at almost $18 billion with help from a surprise surge in wide-body demand.

Airbus¡¯s first-day tally was $15 billion, according to data compiled by Bloomberg. The planemakers¡¯ standing at the aviation industry¡¯s oldest and largest trade event reversed their opening rankings at last year¡¯s Farnborough Air Show, which alternates with the Paris expo.

¡°There¡¯s more commercial activity than I expected,¡± said Richard Aboulafia, an analyst at Fairfax, Virginia-based consultant Teal Group. ¡°The market¡¯s still pretty buoyant. It¡¯s good to see some twin-aisle sales because that¡¯s where there are some gaps in the backlog.¡±
