When you look at airlines boarding processes, they range from a couple of letters (Southwest), to 9 different groups (American Airlines), to a few zones (Delta).

At Delta, they’re adding a new zone to their boarding process, as the airline continues to implement new boarding processes including pillars, and even self-boarding, according to a one gate agent.

The latest change is that they’re rolling out a Zone 4 for Basic Economy passengers. As a reminder, those who purchase Basic Economy on Delta, board in the last group, so we can assume that Zone 4 will be for Basic Economy passengers.

As a reminder, Delta currently breaks down boarding by fare class for non-elite members, if you’ve noticed that, pay attention the next time you fly for you non-Medallions.

Here’s a look at Delta’s New Boarding Structure: 

• Premium: Delta One, First Class, and Diamond Medallion members
• Sky Priority: Delta Comfort+, Platinum and Gold Medallion members, Sky Team Elite Plus
• Zone 1: Silver Medallions, American Express Gold, Platinum and Reserve Delta SkyMiles Credit Card members, Sky Team Elite members, Crossover Rewards SPG Platinum members, Bulkhead rows and Exit Row seats
• Zone 2: Main Cabin Fares in the following fare classes: Y, B, M, H, Q, K
• Zone 3: Main Cabin Fares in the following fare classes:T, X, and V
• Zone 4: Basic Economy Passengers: E fare class

In many of their stations, they’ve also started implementing the new pillar boarding pictures above, so with this new change, expect to see a change to this as well.

What are your thoughts of Delta adding Zone 4 to their boarding process? Do we think more changes will be coming such as limiting carry-on bags for this zone?
