运输行业一直准备迎接疫情奥运会前的人群这个假期，但现在美国两家主要航空公司被迫主动取消了一些平安夜航班，原因是新冠肺炎的omicron变体快速传播。

截至周四晚上，联合航空公司已经主动取消飞往平安夜的112次航班。

联合航空在一份声明中表示:“本周全国范围内奥米克隆病例的激增对我们的机组人员和运营人员产生了直接影响。“因此，我们不幸不得不取消一些航班，并在受影响的客户来机场之前提前通知他们。”

该航空公司补充说:“我们对中断感到抱歉，并正在努力为尽可能多的人重新预订机票，让他们踏上度假之路。

达美航空公司也主动取消了大约90个飞往平安夜的航班。该航空公司表示，“航班取消是由多种问题造成的，包括但不限于某些地区潜在的恶劣天气以及omicron变体的影响。”

达美航空在给美国广播公司新闻的一份声明中说:“达美航空的团队已经用尽了所有的选择和资源——包括改变航线和替换飞机和机组人员来覆盖预定的飞行——然后取消了周五大约90次航班。“我们为客户假期旅行计划的延迟向他们道歉。达美航空的工作人员正在努力让他们在下一趟航班上尽可能快、安全地到达他们需要的地方。”

代表美国所有主要航空公司游说的美国航空公司(A4A)呼吁疾病控制和预防中心缩短完全接种疫苗的个人的隔离时间，称omicron激增可能会造成“重大”干扰。

A4A首席执行官尼克·卡利奥(Nick Calio)周四在给疾控中心主任罗谢尔·瓦伦斯基(Rochelle Walensky)的一封信中表示:“奥米克龙的激增可能会加剧人员短缺，并对我们的劳动力和运营造成重大干扰。

卡利奥建议，对于突破性感染，从症状出现起，隔离期缩短至5天。

“反过来，这些人将能够以适当的测试方案结束隔离，”卡利奥写道。

这封信是在达美航空公司和捷蓝航空公司都是A4A成员之后发出的，这两家公司也要求缩短完全接种疫苗的人的隔离期。

Airlines cancel holiday flights due to omicron impacts on crews

The transportation industry has beenbracing for pre-pandemic-level crowdsthis holiday season, but now two major U.S. airlines have been forced to proactively cancel some Christmas Eve flights due to the fast-spreading omicron variant of COVID-19.

As of Thursday evening, United Airlines hasproactively cancelled112 flights for Christmas Eve.

"The nationwide spike in omicron cases this week has had a direct impact on our flight crews and the people who run our operation," United said in a statement. "As a result, we've unfortunately had to cancel some flights and are notifying impacted customers in advance of them coming to the airport."

"We're sorry for the disruption and are working hard to rebook as many people as possible and get them on their way for the holidays," the airline added.

And it's not just United that'sfeeling the impact of the varianton crews.

Delta Air Lines also proactively canceled around 90 flights for Christmas Eve. The airline says the "flight cancellations are due to a combination of issues, including but not limited to, potential inclement weather in some areas and the impact of the omicron variant."

"Delta teams have exhausted all options and resources -- including rerouting and substitutions of aircraft and crews to cover scheduled flying -- before canceling around 90 flights for Friday," Delta said in a statement to ABC News. "We apologize to our customers for the delay in their holiday travel plans. Delta people are working hard to get them to where they need to be as quickly and as safely as possible on the next available flight."

Airlines for America (A4A), the group that lobbies on behalf of all major U.S. airlines, is calling on the Centers for Disease Control and Prevention to shorten the quarantine time for fully vaccinated individuals, saying the omicron surge may create "significant" disruptions.

"The omicron surge may exacerbate personnel shortages and create significant disruptions to our workforce and operations," Nick Calio, A4A's CEO, said in a letter on Thursday to CDC Director Rochelle Walensky.

Calio proposed the isolation period to be shortened to five days from symptom onset for breakthrough infections.

"In turn, those individuals would be able to end isolation with an appropriate testing protocol," Calio wrote.

The letter comes after Delta Air Lines and JetBlue Airways, both A4A members, also asked for isolation periods for fully vaccinated individuals to be shortened.
