Delta Air Lines has a lower P/E than the aggregate P/E of 13.38 of the Passenger Airlines industry. Ideally, one might believe that the stock might perform worse than its peers, but it's also probable that the stock is undervalued.

Starting today, U.S.-based travelers can now use Venmo to pay for flights at checkout, the airline announced in a statement. This widely used peer-to-peer mobile payment app, powered by PayPal, allows users to send payments to individuals and retailers using their Venmo balance, linked bank accounts, or debit and credit cards.

Venmo payment options are the latest announcement in a broader effort from JetBlue to enhance its services and boost profits. The struggling low-cost carrier has searched for new revenue streams as larger airlines introduce their own budget options, increasing competition for those flyers.

JetBlue (JBLU) is now accepting Venmo (PYPL) as a payment option for flights booked on its website, making it the first airline to do so, the company announced on Tuesday.

A major US airline announced it will accept online booking payments from Venmo to attract younger flyers. Customers are shown a pop-up window with a QR code to scan on the payment app.

"The added ability to pay with Venmo for flights on JetBlue and manage travel costs during the trip through Groups helps solve the pain points of shared expenses from the time of booking to returning home," PayPal's John Anderson, senior vice president and general manager of consumer, said in a statement.

Venmo payment options are available on the airline’s website and will roll out on their mobile app “in the coming months,” the carrier announced.

The ubiquity of PayPal checkout means you'll have many chances to snag a high rewards rate. Non-PayPal purchases, though, earn a less-spectacular rate, and the card lacks a few key features.
