Why it shows up like this
Unreviewed registry note: 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.
Unreviewed registry note: 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.
Common reasons for this charge
Unreviewed registry note: Cardholders often encounter this separate debit days or weeks after purchasing their main airline tickets. Selecting a premium seat during online check-in or accepting a last-minute upgrade prompt in the Fly Delta app triggers an immediate standalone transaction.
- Unreviewed registry note: You selected a Comfort+ seat assignment during booking or check-in on delta.com or the Fly Delta app.
- Unreviewed registry note: An upgrade offer was accepted from the seat map prior to departure.
- Unreviewed registry note: A travel agent or companion added premium seating to your flight segment.
