Despite recent political unrest, Bangkok maintains its position as one of the most important gateway cities in Asia, as well as being a formidable destination in its own right.
One thing that Bangkok is still missing though is some routes from outside London. If you live reasonably close to Heathrow Airport, then you'll have no problem -- direct flights to Bangkok from London's biggest hub airport are available from four different airlines. Unsurprisingly, British Airways and Thai Airways serve the route, and they are also supplemented by Qantas and the Taiwanese airline EVA, who operate their flights to Taipei via Bangkok. Note that Qantas are withdrawing their Bangkok flights in March.
Connecting flights to Bangkok
If you are looking for the cheapest flights to Bangkok, the chances are that you'll end up having to go via somewhere else -- and there's no shortage of options here, whether you're starting in London or from just about any other regional airport with an international connection.
One prominent option is to travel via Dubai, and flights via Abu Dhabi are also available from Manchester and Dublin. Otherwise, you'll end up either connecting through London or one of the main European hubs.
Cheap flights to Bangkok (budget airlines)
Bangkok might seem like an obvious destination for budget airlines to offer cheap flights from the UK, but we are not aware of any plans to launch such a route. The main reason is that there is already extensive competition between the mainstream airlines on the London to Bangkok route, which is still bolstered by it being part of the Kangaroo route to Australia, even after QANTAS exit the market.
As we saw with the demise of no-frills carrier Oasis Hong Kong in 2008, it is very difficult for a low-cost airline to compete in such a hostile environment, especially as the big boys will have no qualms about temporarily slashing their fares in order to kill off any competition.
With fluctuating oil prices, and continuing uncertainty over the economy, don't expect anyone to start offering bargain basement flights to Bangkok in the near future.
Given the recent expansion in flights to Asia from Gatwick airport, I wonder whether or not a route will be added from here to Bangkok by any of the established airlines who might be interested in the route?
