New wing designs, and new engines hanging from them, could change the way we fly. Or at least make it more efficient.

Can Russia produce more than 300 commercial aircraft by the end of the decade to backfill the Boeing and Airbus frames that will be inoperable by then? And would you fly on one if they do??

So much noise for a handful of new routes. Is it really worth the hype? Plus an airline blocks customers and a hotel sues its parent brand.
