请教各位一个问题，不是很确定。
给岳父母换了两张头等舱机票，让他们享受一下。从上海到芝加哥转机然后到凤凰城。
我想问一下他们这种从上海到芝加哥是global first，从芝加哥到凤凰城就是一般美国
国内头等舱的能不能进芝加哥机场global first lounge？
他们在芝加哥有5个小时转机时间，想让他们休息的好一点。打了United的电话没人接
，发email没人回。给他们寄了两张united club的pass结果路上寄丢了。
united的网站上是这么定义的，
Access policy
The following customers may access the United Global First lounge by showing
their United boarding pass for a flight arriving or departing on a same-day
(within 24 hours) itinerary.
United Global First customers traveling on long-haul international flights*
Star Alliance™ First customers departing on international flights
These eligible United Global First Lounge visitors are allowed one adult or
child to accompany them as a guest.
我的理解是，坐国际头等舱到达芝加哥的也是可以的？
谢谢
