Wow, The Airline continue to offer even less for economy fares!

Delta Air Lines last week added a new bottom rung to its fare ladder with the launch of Basic Economy, which comprises the carrier's "lowest-priced fares" and does not allow refunds, changes or advance seat assignments.

A main difference between Basic Economy and other advance-purchase, nonrefundable economy fares is that ticketholders cannot select their own seats. Instead, Delta indicated that seats "will be auto-assigned for Basic Economy fare holders during check in."

The biggest difference is that no changes, or refunds are allowed at all.

The new fare is available through GDS channels and Delta noted that they likely would land at the top of fare search results, especially for travel agencies and self-booking tools that default to the lowest available fare.
"Trip Extras," that would be an extra fee include: priority boarding in certain markets, frequent flyer mile bundles and inflight Wi-Fi access. Additionally, Basic Economy ticketholders the ability to choose a seat, but only at check-in.

Delta added that the new fare class would be identifiable to agencies "with an E as the first letter of the fare basis code or E class of service in schedules and availability displays."
