Yes, several versions of the Delta American Express card provide Zone 5 Priority Boarding on Delta and Delta Connection flights. This benefit is standard for the Delta SkyMiles Gold, Platinum, and Reserve cards (including their respective Business versions). It allows the basic cardmember and up to eight other passengers traveling on the same reservation to board the aircraft before the general boarding groups. This is a significant perk as it virtually guarantees space in the overhead bins for your carry-on luggage. It is important to note that the Delta SkyMiles Blue card does not include this priority boarding benefit. To utilize this perk, you must ensure that your SkyMiles number is correctly linked to your reservation at the time of booking. For those who hold the Delta Reserve Card, you may also receive "Upgrade Priority" over other passengers within the same Medallion tier, further enhancing your travel experience. While Zone 5 is not the very first group to board—it follows First Class and Diamond Medallion members—it is a major step ahead of the "Main Cabin" and "Basic Economy" groups, making it a highly valued feature for frequent travelers.
