LONDON— Delta Air Lines (DL) continues to enforce a decades-old policy requiring passengers to present the original credit card used for booking at check-in — a rule that has left several travelers stranded abroad.

The policy, once common in the 1990s to combat credit card fraud, has left several travelers stranded abroad. The issue has drawn attention after multiple passengers reported being denied boarding at London Heathrow Airport (LHR).

Delta’s Old Credit Card Policy

Delta Air Lines defends its rule as a fraud prevention measure. According to the carrier, travelers may be required to show the original payment card and a matching photo ID, depending on the billing address or country of departure.

When the passengers could not produce the same credit card used for the purchase, the check-in systems blocked them from proceeding. Some travelers were then told their only option was to buy new tickets — costing up to $6,000 — or cancel their trips altogether.

However, many passengers say they are never informed of this requirement during the booking process, leaving them unprepared when they arrive at the airport.

One passenger checking in for a flight from London to Seattle (SEA) said Delta agents refused to proceed without the card used for purchase, reported View from the Wing.

They were stranded until a neighbor in Seattle broke into their home to photograph the card, which Delta eventually accepted. Similar stories have surfaced online, with frustrated customers calling the rule outdated and unfair.

Outdated Fraud Prevention

The policy dates back to the late 1990s when in-person verification was a common step for credit card purchases. At the time, travelers who bought tickets directly from airlines often needed to visit ticket counters to verify the card before travel.

Today, online payment systems and fraud prevention technologies have made such procedures largely obsolete, and other major airlines no longer enforce similar checks.

Travel experts note that this rule disproportionately affects travelers departing from airports outside the United States.

Those booking flights for friends or relatives face particular challenges, as the ticket holder may not have access to the original payment card.

Passenger Rights in the UK

For passengers departing from the United Kingdom or the European Union, consumer protection laws such as UK261 and EU261 require airlines to provide compensation when denied boarding is not justified by documentation or safety concerns.

Since a payment card does not qualify as a travel document, legal experts argue that Delta’s refusal to check in passengers solely for this reason could expose the airline to claims of £260 to £520 per passenger.

Delta has yet to comment on whether compensation is offered to affected travelers, though passengers report that the airline rarely provides refunds or alternative travel options in these cases.

Bottom Line

In 2025, Delta’s insistence on a 1990s-era credit card verification process continues to frustrate international travelers and expose the airline to criticism.

As digital transactions and secure payment verification methods evolve, industry observers say the policy appears increasingly outdated and inconsistent with modern travel standards.

For now, travelers booking Delta flights from abroad should carry the original payment card to avoid being denied boarding — or consider using a travel agency for bookings made on behalf of others.
