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.

>>European and U.S. airlines years ago underestimated the threat posed by short-haul discount airlines. Since then legacy carriers have treated transatlantic low-cost airlines as serious competitors. But there’s reason to believe the low-cost model may not be as appropriate for longer routes. Legacy carriers might be OK this time: Delta CEO Dismisses Threat From Low-Cost Transatlantic Airlines

>>Does the average traveler care whether a U.S. airline CEO made $7 million or $13 million last year? It’s highly doubtful. Passengers want to fly a well-run, on-time airline with friendly customer service. How much money the CEO makes is probably immaterial to most customers: These U.S. Airline CEOs Made the Most Money Last Year

>>United’s new vice president of loyalty wants to bring more value to MileagePlus customers across a wider spectrum of travelers. He’s starting that process by spearheading an overhaul of the company’s co-branded credit card: United Loyalty Boss Luc Bondar Relaunches Explorer Card to Compete With Premier Rivals

>>You probably can’t blame airlines for delivering a poor in-flight Wi-Fi experience. As United’s chief digital officer Linda Jojo says, it’s likely impossible for any provider to give passengers a consistent ground-like experience. People forget sometimes they’re traveling more than 500 miles at hour, at more than 30,000 feet: Skift Tech Forum Preview: United’s Chief Digital Exec on Fixing In-Flight Wi-Fi

>>Nothing refocuses airline executives like rising fuel prices. If they continue to creep up, expect airlines to cancel more marginal routes: U.S. Airlines Lose Tolerance for Money-Losing Flights as Fuel Prices Rise

>>Travelers board an airplane and expect the Wi-Fi, which is often expensive, to work as it does at home. But it’s not as good as at home, and it may never be. Should airlines do a better job of communicating that to customers? Do Airlines Overpromise With In-Flight Wi-Fi?
