导致COVID-19的新冠状病毒的传播减少了人们的旅行欲望，导致航空公司暂停或减少航班，并为客户提供改变计划的豁免。
截至周二，包括美国在内的73个国家的官员已向世界卫生组织（WHO）报告了90,000多例病例。中国受到的影响最大，超过80,000人被感染。在中国境外的病例中，约有80％发生在三个国家（伊朗，意大利和韩国），但环球旅行受到了打击。
总裁罗杰·道（Roger Dow）表示：“冠状病毒存在很多不确定性，而且很明显，这对旅行需求产生了影响，不仅对中国，而且不仅对国际，而且对国内商务和休闲旅行也有影响。”美国旅行协会首席执行官兼首席执行官在一份声明中说。
世卫组织称，达美航空周三宣布减少飞往日本的每周航班，根据需求量减少，日本有268例。
从东京到俄勒冈州波特兰的往返航班；名古屋到底特律和檀香山；从3月7日开始，从大阪到檀香山的大阪航班将从每天的航班时刻表减少到每周3次。从东京到亚特兰大和明尼阿波利斯的每日往返航班每周仅运营5次，直到4月30日恢复全面服务为止。
达美航空表示，西雅图和大阪之间的夏季夏季航线将于2020年暂停运营，并于2021年恢复。受影响的客户可以在4月30日之后重新预订替代航班或起飞的航班，或获得退款。联合航空还暂停了飞往东京的部分航线。
据美国疾病控制和预防中心称，1月21日，华盛顿成为第一个报告新冠状病毒病例的州，其病例数已增加到27。在发现第一例病例五周后，疾病预防控制中心官员报告了第一例死亡，其中一名五十多岁的男子。根据疾病预防控制中心的数据，自星期六以来，又有8人在华盛顿死亡，其中大多数是老年人或有潜在疾病的人，使美国的总死亡人数达到9人。
当唐纳德·特朗普总统周二离开白宫时，他告诉记者，他的政府并未考虑限制国内旅行以防止该病毒传播。
尽管对国内旅行没有任何限制，但联合航空允许人们免费更改3月3日至31日之间预订的旅程，只要在12个月内进行更改且机票的价值等于或小于此值即可。那些想要取消旅行的人可以在原始票证发行之日起12个月内免费将票证价值用于新票证。
副总统迈克·彭斯称赞特朗普迅速限制从中国的旅行。布什总统同时表示，他将考虑扩大对爆发疫情严重的国家（例如意大利和韩国）赴美旅行的限制。
国务院建议美国人重新考虑前往意大利的旅行，如果他们要去意大利，则不要参观已实施本地隔离的伦巴第和威尼托地区。达美航空和美国航空分别暂停了纽约约翰·肯尼迪机场和伦巴第首府米兰之间的航班，直到5月1日和4月25日。达美在肯尼迪国际机场和威尼斯之间的季节性服务已从其最初的4月1日推迟到5月1日。
还建议美国人不要前往韩国，韩国由于大邱爆发而处于三级旅行咨询之下。截至周二，韩国共有4,812例病例，达美，美联航和美国航空都减少了对首都首尔的服务。
为了满足即将出行旅行计划且不希望访问意大利或韩国的合格客户，达美航空和美联航已免收更改费。美国航空还免除了前往意大利的旅客的变更费，但为韩国旅客提供了完全取消的其他选择。
美国旅行协会预测，未来三个月前往美国的国际旅行将下降6％。如果发生这种情况，那将是自2008年金融危机以来国际入境旅行的最大跌幅。
截至周二，由于新的冠状病毒，入境美国的唯一限制是外国人，他们在预期抵达后的14天内已在伊朗或中国。鉴于在中国爆发的疫情，达美航空，美联航和美国航空均暂停服务至4月30日，美联航和美国航空向符合条件的客户提供取消旅行的选择。合格的达美客户无需支付更改费即可重新预订旅行。
陶氏承认人们想知道旅行是否安全，并敦促所有人记住限制和警告是针对暴发地区的。
他说：“目前，绝对没有任何官方指南要求人们重新考虑在美国旅行。”
The spread of the new coronavirus that causes COVID-19 has lessened people's desire to travel, causing airlines to suspend or reduce flights and offer waivers for customers to change their plans.
Officials in 73 countries, including the United States, have reported more than 90,000 cases to the World Health Organization (WHO) as of Tuesday. China's seen the biggest impact, with more than 80,000 people becoming infected. About 80 percent of cases outside China were found in three countries—Iran, Italy and South Korea—but travel worldwide is taking a hit.
"There is a lot of uncertainty around coronavirus, and it is pretty clear that it is having an effect on travel demand—not just from China, and not just internationally, but for domestic business and leisure travel as well," Roger Dow, president and CEO of the U.S. Travel Association, said in a statement.
On Wednesday, Delta announced a reduction in weekly flights to Japan, where there have been 268 cases, according to WHO, because of a drop in demand.
Round-trip flights from Tokyo to Portland, Oregon; Nagoya to Detroit and Honolulu; and Osaka to Honolulu will be reduced from a daily schedule to three times a week, beginning March 7. Daily round-trip flights from Tokyo to Atlanta and Minneapolis will run only five times a week until full service resumes April 30.
Summer seasonal service between Seattle and Osaka will be suspended for 2020 and pick back up in 2021, according to Delta. Affected customers may be able to rebook on alternate flights or flights taking off after April 30 or receive a refund. United Airlines also suspended some service to Tokyo.
On January 21, Washington became the first state to report a case of the new coronavirus, and its case count has grown to 27, according to the U.S. Centers for Disease Control and Prevention. Five weeks after the first case was identified, CDC officials reported the first death, involving a man in his 50s. Since Saturday, eight other people have died in Washington—mostly involving people who are elderly or have underlying conditions—bringing the total death toll in the U.S. to nine, according to the CDC.
As President Donald Trump departed the White House on Tuesday, he told reporters his administration was not looking at restricting domestic travel to prevent the virus from spreading.
Although there aren't any restrictions on domestic travel, United Airlines is allowing people to change trips that are booked between March 3 and 31 for free, as long as the change is made within 12 months and the ticket is of equal or lesser value. Those who want to cancel their trip can apply the value of the ticket to a new one, without a fee, for up to 12 months from the original ticket's issue date.
Vice President Mike Pence applauded Trump for quickly restricting travel from China. Meanwhile, the president said he would consider expanding limitations on travel to the U.S. from countries with significant outbreaks, such as Italy and South Korea.
The State Department advised Americans to reconsider traveling to Italy and, if they were to go there, not to visit the regions of Lombardy and Veneto, where local quarantines were enacted. Delta and American Airlines suspended flights between New York's John F. Kennedy Airport and Milan, the capital of Lombardy, until May 1 and April 25, respectively. Delta's seasonal service between JFK and Venice was pushed back to May 1 from its original start date of April 1.
Americans were also advised against traveling to South Korea, which was under a Level 3 travel advisory due to an outbreak in Daegu. As of Tuesday, there were 4,812 cases in South Korea, and Delta, United and American had all reduced service to Seoul, the capital city.
To accommodate qualifying customers with upcoming travel plans who may not want to visit Italy or South Korea, Delta and United have waived change fees. American also waived change fees for passengers traveling to Italy but gave South Korea travelers the additional option of canceling altogether.
The U.S Travel Association predicted international travel to the U.S. will drop 6 percent over the next three months. If that happens, it would be the largest decline in international inbound travel since the 2008 financial crisis.
As of Tuesday, the only restrictions on travel into the U.S. due to the new coronavirus are on foreign nationals who have been in Iran or China within 14 days of their expected arrival. Given the extent of the outbreak in China, Delta, United and American all suspended service until April 30, and United and American offered qualifying customers the option to cancel their trip. Qualifying Delta customers were able to rebook travel without paying a change fee.
Dow acknowledged that people are wondering if it's safe to travel and urged everyone to bear in mind that restrictions and warnings were specific to areas where there are outbreaks.
"Right now, there is absolutely no official guidance that people need to be reconsidering travel in the U.S.," he said.
