I was looking at some websites to check the likely arrival time in London of this overnight Thai Airways flight. A couple of sites like Flightera say 62% of flights are delayed by an average of about 30 minutes:

https://www.airportia.com/flights/tg910/bangkok/london/

Another website though suggests it usually lands early:

https://www.flightradar24.com/data/flights/tg910/

 

Can anyone shed any light on this? It would help me book onward transportation.

It is possible for departures to be often delayed but for landings to be often on time or early.

True but the first 2 websites both have delays to both departure and arrival. I think the flightrader24 website might be using the wrong time zone (GMT instead of BST). So it does look like the average delay is indeed 30 minutes. It's a typically Thai approach to give an overly optimistic arrival time.

Not the night flight, but similar with TG916 day flight which showed delayed departure every day running up to my departure date. On the day boarding didn't start until 15 minutes before the scheduled departure time and had no chance of departing on time. And arrived 30 minutes late in LHR so expect the same.

 

 

 

 

Thanks that's helpful. I'll book a later coach from Heathrow. Eva Air do a similar day flight but it's scheduled to take half an hour longer so the Thai Airways flight schedule just looks like 'Thai time'.

going the other way tg911 seems to be often delayed -- my one recently by 1hr 15min

 

I travelled return on that route last week, the delays are caused by the closure of Pakistani airspace for flights to and from Thailand and other countries, including India.

 

Flights, including Thai, BA and Eva, have to take a longer southerly route over the India mainland, hence the delays.

 

The Pakistan authorities were considering opening their airspace at a meeting on the 15 May, but put the decision off.

 

My flight was delayed just under an hour to LHR and slightly over 30 mins on the return journey.

 

As you will be aware Thai have two flights a day and both are being delayed.

   

I have checked BKK->LHR on TG, BA and Eva on three days and TG has the biggest delays on all flights although not excessive (<30 min).

BA and Eva manage to remain within the 15 min "on-time" frame.

BA even manages to compensate a 30 min delay in departure to a delay of some minutes on arrival.

But with the India/Pakistan trouble, arriving ahead of schedule is unlikely.
