Regulator demands companies explain how and why they charge different prices for the same product or service

The Federal Trade Commission (FTC) is demanding some of the US’s biggest airlines, ride-share companies and retailers divulge how they are using algorithms and loyalty programs to target customers and drivers with different prices and wages.

Nine companies – Delta, United, JetBlue, Lyft, Uber, DoorDash, Instacart, Target and Walmart – were named in the inquiry, which comes after investigations and lawsuits alleging consumers are charged different prices based on their buying histories and drivers paid different fares based on their personal histories.

• Being a mom can be challenging and expensive.
• Some have turned to apps like Uber and Lyft to make extra money — or as their main source of income.
• Fill out our survey if you're a mom who does gig work.

Uber and Lyft often talk about the flexibility of working as a driver on their apps.

That aspect of the gig has attracted moms, among other people who often want to earn money outside a 9-to-5 schedule. The job can be appealing to mothers who need to juggle school drop-offs, childcare, and other obligations of parenting.

Others, including single moms, say they feel stuck in ride-hailing work and end up having to drive for Uber or Lyft at set times anyway, depending on when the most passengers need rides.

With costs like childcare and college rising, Uber and Lyft offer some moms a way to make extra money — if they can earn enough on the apps and keep costs like gas and car maintenance under control.

Business Insider wants to speak with moms who drive for Uber, Lyft, or other ride-hailing apps. We want to hear about how you combine the gig with taking care of your kids, including both what's working and what isn't. Please fill out the survey below.
