现在很多朋友喜欢参考IATA的Timatic数据库的签证信息，该数据库中各目的地国对于转机，免签，落地签等签证信息一目了然，从某种程度上说也相当准确。

然而，IATA并非政府机构，该机构对提供的签证信息作了很多限定：

2.对于签证及入境，该机构声明除目的地国的移民官员外，承运航空公司的员工也有权或可能拒绝旅客登机或入境。

我举个最简单的例子吧，“新加坡96小时过境免签”VFTF。

从IATA数据库查询得到的信息是，中国公民持有部分发达国家签证，在途径新加坡过境时，来回可以获得一次96小时的过境免签。注意下列规定中，outbound of journey中的journey并没有定义是否往返中国和所持下列发达国家签证的签发国。因此，从字面解释，持有多次有效美国签证未必要走中国-新加坡-美国。

Vis a required, except for Nationals of China (People's Rep.) who can also transit, one time only, for up to 96 hours without a visa under the Visa Free Transit Facility (VFTF) on either the outbound or return leg of the same journey (but not on both). Leaving the transit area is allowed.
- ***Warning*** Holders of a valid single entry visa (or
   multiple entry visa valid for at least one month) issued by

   Australia, Canada, Germany, Japan, New Zealand,
   Switzerland, United Kingdom or USA

to nationals of China (People's Rep.) may use the VFTF mentioned above. After using a single entry visa and the VFTF was not used on the outbound leg of the journey, the VFTF can only be used on the return leg with a direct transit through Singapore from the country that issued the visa to the country of residence (e.g., SYD-SIN-PEK).

假设你持有有效多次美国签证和泰国签证以及中国-新加坡和二天后的新加坡-泰国的机票在北京机场办理中国-新加坡的登机牌，而且你需要托运并在新加坡提取行李，或者你的第二程登机牌必须出境办理。按照IATA的96小时过境免签信息，你应该能获得登机牌。

只不过某航的值机柜员和主任均认为你必须前往美国才能获得上述96小时VFTF免签，因此拒绝为你办理登机牌，你的航班被延误，所有预订的酒店和行程也因此作废。

你当然要维权了，按照IATA信息要求某航损害赔偿。

然而，某航会问你：

1.你要入境新加坡，你有签证么？没有。

2.没有签证，你怎么入境呢？你答曰：新加坡的VFTF96小时过境免签政策。

可是你也许不知道，大概一年多前，该项“96小时免签过境”VFTF的规定就“神秘”地，悄悄地从新加坡移民局的官方网站以及新加坡樟宜国际机场的官方网站消失了。

你说，诺，IATA上写的明明白白。呵呵，看看开头所列的2项IATA的免则规定：一来IATA不从法律上保证数据查询的准确性，二来航空公司职员有权决定给予登机与否。这签证政策可历来都是各国外交部门和移民部门说了算，况且上述适用中国公民的96小时过境免签VFTF政策你连新加坡驻外大使馆领事馆都查询不到啊。

有位网友杨童鞋在韩国过境被拒，就算IATA写明了可以过境，难道你用一份民间的资料去跟移民入境处说：诺，这是你们的规定。你说，有几个会承认？（如果他们没有这项公开政策的话）
