有關 Zuji 訂機票....

Zuji should be OK to use as it is not a small compary... So I believe you can trust it...
After you put in the date you want, that column of information on the left hand column are promotional tickets...
Usually on the main list, they are the cheapest standard ticket that they can find for you... But on the left hand column, its just the promotion that they are doing, so there would be more restriction on those tickets... And sometimes it would be the same or similar to the normal standard ticket when you include all the tax and sur-charge...
Also, although it is shown there of a cheaper price... But it doesnt necessary means that there are spaces on those flights that are sold at that price... As usually the number of these promotional tickets are limited... But you can have a look at them if you find it meet you requirement...
