The show is happening at a delicate time for Boeing, which is coming off its best month for sales in a year and a half and a deadly plane crash in India involving one of its aircraft.

Airbus secured more aircraft orders on Wednesday, raising its total to $21 billion at this week’s subdued Paris Air Show, while rival Boeing opted not to announce new sales following last week’s Air India 787 crash.

Airbus SE wrapped up the Paris Air Show with more orders for its advanced A350 model, making a clean sweep at the event after perennial rival Boeing Co. chose to postpone any announcements following a fatal crash a few days before the expo.
