I've checked the online rates, and it appears it will be much cheaper (not to mention FASTER) to travel from Singapore to Kuala Lumpur via Tiger Airways(43 SGD) than to take the Aeroline coach (.09 SGD!). Why is this? Is there a catch somewhere? I'm a first time traveller to both Singapore and Malaysia, and I could be missing something here. I hope someone could enlighten me. Also, if there are cheaper yet better alternatives than those 2 options, I hope you could share a tip or two. Thank you very much!
