Yo Zhuzhu,
For that price...kekeke.... i would rather choose Reetha Rai, or Hilton Spa Villa.
Kekeke..... IATA no.? don't know leh. One choice is to share IATA no. Liase with some smaller agency for that.
In US, they got some "Direct sales" scheme whereby U can use their IATA no for business but pay them a 1 time fee or yearly fee like that. Then you can form a network below u and take comms from your down-line. More like a Paramid scheme lah.... Beware of such offer.
If wanna to do, must be legal one lah... I'll check out from my friends who are in travel industry.
After getting IATA no., must also register a company lah, then must register with STB(spore tourism board), get sticker, then ppl more convince.
That's all I can think about.
To setup an online travel biz, we must think of a way to be outstanding, cannot operate like GSA or like SA tour like that. We must find the niche loh...
Can discuss further....
