This week's dispatch

Business-class kids

Although the peak of summer travel has passed, there are still plenty of families taking advantage of better deals and smaller crowds for last-minute trips. For some, that might mean flying business class — and bringing their kiddos along, too.

Sara Arbelaez-Chujfi told Business Insider reporter Maria Noyen earlier this year that her 2-year-old had already flown 80 times, half in business class.

Arbelaez-Chujfi said there's more personalized attention in business class, from flight attendants babysitting her daughter when she has to use the restroom to holding the bathroom door open when she needs extra space to change her daughter.

The extra attention, however, comes at an extra cost. According to travel company Going, the price of a single business class ticket typically ranges from $3,000 to $5,000. Now multiply that by all the kids in your family, and you're looking at quite the splurge.

Still, some have managed to score more affordable business class flights in a few ways, including bidding on upgraded seats or using points. That's what Jill Robbins did when trekking from San Antonio, Texas to Tel Aviv, Israel with her 13-year-old son.

Whether you splurge or find a deal, you shouldn't feel out of place bringing the kids along. Flight attendants told BI they don't mind having children in business class and will provide hands-on service regardless of the passengers' age.

"In business class, we have a lot less people to cater to and you are paying for more of an experience. So that's what we give," one American Airlines flight attendant said.

Fall fashion must-haves

Was that a chill in the air?

September is upon us, which means it's time to transition to cooler-weather wardrobes. This year, fall fashion is about comfort, style, and luxury. The season's biggest status symbols include an $850 suede coat and a pair of $168 men's clogs, which you can don as you crunch leaves beneath your feet and sip that Pumpkin Spice Latte.

A little commotion for the spa

Known for her elaborate wellness routines and products, it should come as no surprise that Gwyneth Paltrow has an extravagant at-home spa. But she's not the only one with luxurious health and wellness rooms.

Around the country, architects are fielding requests from wealthy Americans wanting flashy new fitness dojos. From hyperbaric chambers to cold plunges, one residential architect shared some of the most lavish projects his team has worked on.

Big sisters actually have it the worst

Science might finally prove what many women have known all along: Eldest-daughter syndrome is real.

The premise relies on two core assumptions: Firstborn or only daughters are expected to be role models for their siblings, and are asked to take on more housework than their brothers. Studies show there are very real benefits for the parents and siblings of firstborn daughters. Whether that carries over to the daughters in question is a different story.

Why you should thank your big sis.

Tulum's quiet side

For some travelers, Tulum feels like it's lost its appeal. But those people haven't stayed at La Valise, a small boutique resort located in the heart of the vacation destination's busy hotel zone.

Widely considered one of Tulum's top resorts — it even has a perfect score on Tripadvisor — La Valise feels like stepping into a dream. Two nights at the boutique resort prove that tranquility is a luxury all its own.
