Macau to Kunming (travel options)?

I need to get to Kunming from Bangkok (but the direct flight is a bit pricy). I know Bkk-Macau is a good option on AirAsia but I don't know how to get from Macau to Kunming?

What airlines fly from MACAU-KUNMING?

How much does a one-way ticket go for?

Is there an overland option I should consider (ie. sleeper train?)

and finally, entering Macau only requires a Chinese visa and passport right?

It would have been better if the question had been asked in the Travel section, maybe you can get it moved.

To answer some of your questions.

"and finally, entering Macau only requires a Chinese visa and passport right?"

Entering Macau needs a Macau visa. There are exceptions, eg visa exemptions. Best to go to the official Macau tourist website to find out if you country is on the list. If you do need a visa then this can be obtained on arrival, although there will be a charge. travellers into Mainland China need to go through Macau immigration.

Whist technically Macau is once again part of China, as far as air travel is concerned a flight from Macau to Mainland China is classed as International and has a corresponding price tag. The same can be said for Hong Kong. I know that Air Macau fly from Macau to Kunming but only twice a week. I also believe that China Eastern fly between the two cities, but am unsure how often.

Obviously a flight from Macau to Kunming will also require a valid Chinese visa

Other alternatives for you could be:

Flying Yunnan Airlines (probably cheaper than Thai)

Flying Thai from ChiangMai to Kunming

Flying to Hong Kong and then going over to either Shenzen or Guangzhou by land then catching an internal flight.

You possibly could also fly to Macau and go over land to the nearest airport

Hope of some help
