By Joe Brock, Tim Hepher, Giulia Segreti and Paul Sandle PARIS (Reuters) - Airbus struck a deal with budget airline VietJet for up to 150 single-aisle jets at the Paris Airshow on Tuesday, where industry hopes for a return to tariff-free trade were given a boost by U.

Boeing had a more muted tone than its European rival. The show comes soon after a Boeing jet operated by Air India crashed.

Vietjet and aircraft manufacturer Airbus on June 17 announced a major new order for 100 A321neo aircraft, with the potential to add another 50 in the future.
