How to book Fare Class W

Information about booking Fare Class W on Delta Air Lines.

Fare Class W is marketed as a Comfort+ revenue fare class. While there aren’t many Comfort+ fare classes, the fare basis code is what is used to calculate pricing on the W fare class. Unfortunately, fare basis codes have been eliminated from Delta.com and the flight receipts over the years to obscure pricing and fare rules from the consumer. If you’re looking for flights and see Fare Class W showing as the lowest fare class available, it means there is availability in the Comfort+ cabin.

Tickets purchased in Fare Class W will set by the fare basis code. To book a cheaper fare class, make the following changes (if you can):

• Adjust your departure/return dates
• Search for alternate airports or co-terminals
• Search for alternate routing
