Understanding Airport Sequence (SEQ): A Guide to Check-In Order

When checking in at an airport, you may notice a code on your boarding pass that begins with “SEQ” followed by a number. This code, known as Sequence Number (SEQ), indicates your position in the check-in queue.

What is SEQ?

SEQ is an abbreviation for “Sequence.” It is a sequential number assigned to each passenger who checks in for a flight. The SEQ number is usually displayed on the boarding pass and corresponds to the order in which passengers checked in.

How is SEQ Determined?

The SEQ number is typically determined based on the following factors:

• Time of Check-in: Passengers who check in earlier will generally have lower SEQ numbers.
• Priority Status: Elite frequent flyers, first-class passengers, and passengers with disabilities may receive higher priority and thus lower SEQ numbers.
• Check-in Method: Passengers who check in online or through self-service kiosks may also have lower SEQ numbers compared to those who check in at the airport counter.

Significance of SEQ

The SEQ number can be useful in understanding your position in the boarding process. Lower SEQ numbers generally indicate that you will board earlier, while higher SEQ numbers may result in longer wait times. However, it’s important to note that boarding times can also depend on other factors such as the airline’s boarding procedures and passenger flow.

Example

For example, if you have a boarding pass that reads “SEQ/017,” it means that you were the 17th passenger to check in for your flight. This does not necessarily mean that you will be the 17th passenger to board the aircraft, but it does give you a general idea of your position in the boarding queue.

Conclusion

The SEQ number on your boarding pass provides a convenient way to track your progress through the check-in process and understand your approximate boarding time. By paying attention to the SEQ code, you can make informed decisions about when to arrive at the gate or whether to take advantage of priority boarding options.
