United Airlines will introduce a new boarding process to streamline the boarding experience.

• Beginning Oct. 26, United Airlines will board economy passengers with window seats before those with middle and aisle seats, as stated in an internal memo.
• United estimates that the new boarding method will save up to two minutes of boarding time.
• The change does not affect passengers in first class, business class, or the preboarding group.

Economy-class passengers with window seats will board first next week, while those with middle and aisle seats will follow.

The company said the change could shave two minutes off the boarding process.

According to a company memo shared with CNBC, the new procedure will begin on Oct. 26 and boarding times have increased by up to two minutes since 2019 at United.

Airlines frequently adjust boarding processes to maximize efficiency, offering priority boarding to their most valuable customers. However, a delay in departure due to disorganized boarding could lead to a chain reaction of disruptions, causing delays in aircraft and travelers' arrival at congested airports.

According to the memo, United's boarding process for travelers with disabilities, active duty military members, young children, and elite frequent flyers in Group 3 will remain unchanged.

Passengers with window seats will board first, followed by those with middle seats and then aisle seats, United announced. People on the same reservation, such as families, can board together.

All domestic flights and select international flights will undergo a new boarding process.
