Delta offers several fare products including Basic Economy, Main Cabin, Delta Comfort +, as well as First/Business Class fares, and generally they get more expensive in that order.
However, I was searching on a recent flight from Las Vegas to New York (JFK), and noticed that Delta was selling some Basic Economy fares for the same price as Main Cabin fares.
After doing some more research, it seems like the error is in the Basic Economy fares prices, which should be less than the Main Cabin fares as other days these were running for $98.
Perhaps, Delta decided to not match the other low-cost carriers on this route such as JetBlue and instead of removing the Basic Economy fare option, they increased it to the Main Cabin fare, which isn’t the route I would of gone.
As a savvy traveler, you’d know to book the Main Cabin fare, but I can’t help but think some people are out there buying these Basic Economy fares.
