英语翻译再是候机.在候机厅那里休息,等广播通知登机.最后是登机.听到登机广播后,在登机口会有服务人员撕登机牌,你就到登机

Then it's waiting for the flight.You can take a rest at the departure hall until you hear the onboard broadcast.
Finally it's onboarding the plane.After the onboard broadcast,there will be ground crew checking the boarding pass at the gate.They will tear off a small piece from the boarding pass and return the pass to you.Then follow the others onto the plane with the pass.
This is the service provided by the ground crew when we are taking the fight.
对于你的翻译内容：
1.之前还有安检的程序不知道你是不是已经翻译了.
2.等待飞机应该是在登机口那里了,不知道你是否会造成对方误会
