全球比较大的航空公司大部分都加入了某一个airline alliance, star alliance, oneworld or skyteam

具体数据请参考

CZ(china southern)好像已经或者快要加入skyteam了

如果仔细看一下，JL(japan airline小日本航空)好像不属于任何一个, malaysia air system不属于, 不知道这两家想干什么，不过个人认为，JL很可能加入oneworld，因为star alliance有ANA，skyteam有korean air，而oneworld没有日韩的航空公司，马航是不可能去star alliance的，因为有新航，觉得倒是skyteam更有希望一些。

然后看看大中国地区吧，只有CX正式加入了，CZ可能是skyteam的，CA很可能是要加入star的，因为跟lufthansa关系比较好，有code sharing，如果前二者都是真的话，MU只能去oneworld了。另外，CI和BR(eva air)还不清楚，也没有听说他们有什么code sharing，不知道大家有什么小道消息。

最近nwa不行了，故意削减地勤和维修人员25％的薪金，然后工会就会闹，然后就有理由申请破产保护，估计明年第一季申请破产保护，delta也想这么搞，不过还没有什么具体的行动，如果都这样搞，那skyteam就掉得大。

另外我一直不太清楚code sharing是怎么回事，比如说SQ和NZ share code，是不是一天由SG的飞机飞，一天由NZ的飞机飞，然后卖票还是分开的？坐过的筒子讲一下，因为我发现share code的飞机总是在同一时刻发机的。

UA, TG, NW, Continental 居然都做过？？

去年就定下来了，只是给点时间让他把服务质量搞上去。呵呵……

alliance主要还是要看大家的strength有没有互补性，像中国这样一个很封闭的航空市场，其实加入哪家都一样。

航空业主要是没有巨无霸级的公司，航运业里面的前三名都不是任何alliance的，只有3名之后的航运公司才搞alliance。

大的航空公司几乎全部加入了alliance的。
比如AA(最大的航空公司）---one world. UA(second largest)----star alliance, NWA----skyteam. Air-France&KLM----skyteam, 汉莎---star alliance, BA-----one world.ANA---star alliance

Delta不知道，也就是这些世界知名的大公司全不都是联盟的，本来这些联盟就是他们搞出来的。小公司才是不去联盟。

MAS估计是skyteam的，因为他和NWA的合作一直有。
MU很可能是one world,因为他也是Asia mile的成员，里面很多成员都是one world的。

我不知道庸人说的前三名是哪三个

Delta是skyteam的创始公司。

世界前三大航运公司：马斯基，地中海和长荣。

比如说 British Airway 和 Qantas 在新加坡到英国的航线上有code sharing.

如果实际上是Qantas的航班，会说 BAxxxx operated by Qantas. 在告示牌上出现两个航班号，各用各的。旅客享受完全待遇

三年前的事了. skyteam的mileage可以换成JAL的mileage.

是不是因为现在由于油价升高，航空公司怕以后负担不了所以买个保险之类的东西呢？

接受破产法保护后，航空公司可以避免债主逼债的困扰，使他们可以继续维持营运，并设法降低成本与清偿债务。

Northwest, Delta file for bankruptcy protection
No impact seen on airlines' passengers

By Peter J. Howe, Globe Staff | September 15, 2005

Reeling from low-cost competition and crushing debt and pension costs, Delta Air Lines Corp. and Northwest Airlines Corp. filed for bankruptcy protection last night, pushed over the edge by soaring jet fuel prices in the wake of Hurricane Katrina.


With the filings, four of the seven largest US airlines will now be operating in Chapter 11. Delta and Northwest are joining UAL Corp.'s United Airlines and US Airways Group Inc. Just under half of all airline-flight seats available in the US are now being operated by bankrupt airlines, according to the Air Transportation Association, a trade group.

US airlines have struggled for years to bounce back from the aftermath of the Sept. 11, 2001, terrorist attacks, which struck when the industry was already facing deep strains and scant profits before travel demand plummeted.

But so-called legacy carriers like Delta and Northwest that carry big debt and pension loads and operate expensive hub-airport operations have been especially hard hit. They have struggled to compete with low-cost upstarts such as Southwest Airlines Co. and JetBlue Airways Corp., and Delta has even tried to push into the low-fare market with its own brand, Song, which also sought bankruptcy protection yesterday.

The bankruptcy filings are likely to hurt Delta and Northwest stock and bond owners, potentially leaving their investments worthless. But analysts and airline executives agreed that it should be a virtual nonevent for passengers. Delta is the second-biggest airline at Logan International Airport in Boston after AMR Corp.'s American Airlines, serving roughly 100,000 passengers a week, or 20 percent of Logan traffic. Northwest is a distant fifth at Logan, serving 5 percent of passengers, according to airport statistics.

Btw, 小蹦，现在在哪里工作呀？
