因为优先的太多了，银卡是优先的底层（Group 2）：
We’re dedicated to providing convenience and comfort throughout your journey with United and are always looking for ways to improve your overall experience. Our customers have told us they want a better experience when boarding, so we’re unveiling just that.
You will see some new boarding lane signs in the gate area that will guide you through the boarding process. There will now be two lanes that are color coded: to begin, Group 1 will board through the blue lane and Group 2 will board through the green lane. The remaining Groups 3-5 will then board through the green lane when called, and Groups 1 and 2 can continue to board through the blue lane.
We encourage you to make yourself comfortable while you wait for your group to be called, and we’ll let you know when we’re ready for you to board. Late arriving customers in Groups 1 and 2 are welcome to continue boarding through the blue lane at any time.
