The short answer
A charge labeled DELTA* COMFORT PLUS represents a seat upgrade, extra legroom fee, or fare difference billed by Delta Air Lines, Inc.
Why it shows up like this
A line item identified as DELTA* COMFORT PLUS indicates an ancillary airline purchase processed by Delta Air Lines, Inc. Rather than covering a complete flight reservation, this specific descriptor represents a Delta Air Lines Comfort+ Seat Upgrade, providing passengers with extra legroom and dedicated overhead bin space. Depending on the clearing network, statement descriptions can also appear as DAL*COMFORT PLUS, DELTA AIR LINES SEAT, DELTA AIR 006, or DELTA SEAT UPGRADE. Similar to seating upgrades offered by United or Southwest, these fees are settled separately from base ticket purchases.
The charge occurs when an upgrade is chosen during initial booking or added later through the Fly Delta mobile app or delta.com website. Even if your original ticket was purchased weeks earlier or booked through a corporate portal or travel agency, selecting a Comfort+ seat creates a new, standalone debit on your payment card. Because airlines issue upgrades as Electronic Miscellaneous Documents (EMDs), the transaction posts independently from the original ticket price, typically ranging from $29 to well over $150 per flight segment based on distance.
If you do not recognize this charge, check your upcoming flight itineraries in the Fly Delta app under the My Trips tab. Confirm whether a traveling companion or family member on the same reservation upgraded their seat assignment. Delta also allows passengers to cancel seat upgrades for flight credits or full refunds within 24 hours of booking, or if an equipment swap downgrades you back to standard coach. If you did not purchase this upgrade and have no pending travel with Delta, contact your financial institution to dispute the charge as potential card fraud.
