Sichuan Airlines A350-900

Yes. The one-two-one layout gives all seats their own path to the aisle, so nobody steps over anybody. It is the airline's strongest cabin and the reason to favour the A350 over the A330s when both serve your route.

The window seats, tucked in against the shell of the cabin where the privacy is greatest. The centre pair puts two seats side by side, which suits couples and is the sociable half of an otherwise private cabin.

No. Sichuan configures its A350s with two cabins, business and economy, so the middle ground you find on some other carriers' A350s does not exist here. The step up from economy is the full business fare.

The bulkhead rows for knee room and bassinet positions, and a window or aisle anywhere else to stay off the middle of the nine-abreast centre block. The forward rows are calmer and clear the aircraft sooner.

A close sibling whose front cabin runs a little deeper and whose economy differs only at the margins. The layouts match, so seat advice carries over between the two without adjustment.
