DBS x Singapore Airlines: S$50 off flights. Book by Aug 17.

Southwest is running a sale with up to 40% off base fares on select routes and dates, but the blackout dates are extensive and not every flight qualifies. The discount applies to both cash and Rapid Rewards bookings, but don't assume it's a true deal — Southwest often marks up prices before these sales, so compare against yesterday's fares. If you have an existing booking on a Choice fare or higher, you can change to the new lower price and get the difference back as travel credit; Basic fares are locked in and ineligible.

KLM will replace its infamous free cheese-filled half-sandwich on European Economy flights with a buy-on-board service called Grand Café KLM, starting in October. Passengers will still receive a free stroopwafel and a choice of tea, coffee, water, or orange juice. After that, a cart will offer items for purchase, including a salmon egg wrap, yogurt with fruit and seeds, and pre-order options like poke bowls and Caesar salads. KLM says the move, tested for over a year, is about offering more choice, but it also aims to shore up lagging financial performance. Only Air France and ITA Airways remain among major European full-service carriers still providing free snacks and drinks in short-haul Economy.
