航空公司可能是受禁令影响最直接的公司，禁令禁止7个国家的公民进入美国，甚至那些以前持有有效**或美国绿卡的人。

这些航空公司别无选择，只能配合美国海关和边境巡逻队的指示，即使它们处理的是乘客，当然还有不能再进入美国的雇员。

The Verge已经联系了多家航空公司征求意见，我们将在收到回复后更新此帖。

更新1月29日，12:37美国东部时间：CNN报道说，在国土安全部有一些混乱的命令是否影响合法的永久居民-也被称为绿卡持有人。发给航空公司的指南中有这样一句话：“合法的永久居民不包括在（禁令中），可能会继续前往美国。”这句话被证明是不正确的，尽管一些绿卡持有者在严重延误后最终获准入境。这就解释了以下几家航空公司发表的声明中措辞不一致的原因。

三角洲航空公司

An Executive Order issued on Jan. 27 has suspended for 90 days the entry into the United States of most immigrant and non-immigrant "aliens [8 USC 11101(a)(3)]" from the nati*** of Libya, Iran, Iraq, Somalia, Sudan, Syria and Yemen.

· C-2 visas for travel to the United Nati***;

On 28 January 2017, President Trump of the United States of America signed an executive order that has immediate c***equences for passengers from seven countries: Iraq, Iran, Syria, Sudan, Somalia, Libya, and Yemen. As a result, KLM was compelled to inform seven passengers on Saturday that they would not be able to fly to the USA.

Like all other airlines, KLM has to comply with the entrance requirements that countries set for travellers. Airlines are not permitted to carry passengers who do not meet those entrance requirements. In this, KLM complies with the aviation authorities’ international agreements.

KLM regrets the inconvenience caused to its passengers who were confronted with this sudden change of circumstances. Although the fact that these passengers were unable to fly to the USA lies entirely outside KLM’s sphere of influence, we decided to offer these passengers a voucher equivalent in value to the flight they were unable to take to the USA. KLM thereby hopes to alleviate to some degree the inconvenience caused by the decision taken by the American authorities.

KLM now informs affected passengers prior to departure. Passengers who were already on their way to Schiphol have been offered a free flight back to where they departed from. No KLM passenger has got stuck anywhere.
