关于托运箱子的尺寸问题

我知道托运的两个大箱子的尺寸是三边之和158厘米，23公斤重。可我在网上还看到，有人写他带的箱子尺寸是30'的。但我买的箱子上标的尺寸是 62*77*34,三边之和超过158了，号码却是30号。售货员说没问题，他们经常卖给出国人员的。
   我现在担心这个尺寸行不行，加航对大箱子的尺寸要求严不严？还是重量不超就行了呢？

   出国前我在这儿得到了大家很多的帮助，谢谢各位！

刚刚搜索了一下论坛，楼主查看一下这个链接先。
应该会有帮得上的信息。

谢谢就是一枪！尺寸我是知道的，而目前我的箱子总尺寸超了十多厘米。以你们已经出去的人的经验，大箱子他们一般量不量尺寸？

Airline normally wouldn\'t  measure it, but weight is very very sensitive, not over 23 kg, otherwise---surcharge!! (my friend got charged $37CAD for over 10 lb)

for irregular size luggage will not have extra charge, it will only given a sticker and send to special care unit, like sporting luggage, golf, ski equipment.

However the bigger the luggage itself, the heavier it is. So no point you use a super size luggage and filling it half-full, right?

I went back home last year and took all the luggages out to weigh the net weight. super size weight almost 20 lbs itself. midsize weight 15 lbs. 5 lbs of difference, I can bring 5 more pairs of blue jeans

I rather use a midsize luggage to pack 35 lbs of belongings.

只要不超重一般就没有问题

谢谢各位指点，这下我就放心了。
