Throughout the week we post dozens of original stories, connecting the dots across the travel industry, and every weekend we sum it all up. This weekend roundup examines aviation.

For all of our weekend roundups, go here.

>>Even if they buy first class pajamas, an upgraded meal, and an amenity kit, coach passengers still won’t feel like they’re in a premium cabin. But at least some airlines are giving travelers the chance to buy up to a better experience. It’s cheaper than an upgrade: Coach Passengers Can Get Premium Amenities — For a Price

>>There’s much to look forward to with Air Canada’s new loyalty program — as long as it doesn’t copy too much from American carriers: What to Expect From Air Canada’s New Loyalty Program

>>Airports are the shopping malls of modern times and one of the most effective ways for luxury brands to engage target markets worldwide: Luxury Brands Invest in Airport Pop-Ups to Reach Coveted Customer Base

>>If you’re an investor, it’s not clear Spirit’s model is the right one. But if you’re a passenger, you should love the airline, even if you never fly it.

>>Many airlines sell premium amenities to customers in coach. But is it worth it? Yes, these are high-margin items, but airlines don’t sell that many of them. Most coach customers want only the basics and don’t want to pay extra for anything: Should Airlines Sell Business Class-Style Products in Economy Class?

>>Most experts say airlines should board aircraft randomly if they seek maximum efficiency. But that’s a problem since most carriers want to reward their best customers with early boarding. Under the circumstances, airlines do the best they can: United Airlines May Change Its Boarding Procedures
