The Wi-Fi you see on those 787s is the eLog downlink, it's not for customers, crew don't have access to it. It's for the plane to download its eLog so that the engineers know what they'll need to work on as soon as the plane is on the ground, thus saving the time of having to engage the aircraft, trawl through the log, get a debrief from the crew, decipher other people's writing...

Beware G-STBE, she just ferried me home from GRU but no announcement and no WiFi the whole way. Asked the crew who said they don’t touch/control anything. Hope it wasn’t just the case that they forgot to switch it on!

No this are correct we have no control over the system.

This may be linked to 'reliability issues' with the 2Ku system. Delta use it as well and have been publicly apologising that it's not working properly. Hopefully these are just teething problems on what is, after all, still a relatively new system.
This is from a week ago but there were still issues yesterday:

On a 77W with wifi,working quite well. Can't read the registration from flight radar 24 because of tired red eyes but the connection is good BA168

Soo. 6 months has now passed since this thread was created and we've got 6 aircraft with wifi..

Was on BA 278 yesterday from SJC to LHR on Dreamliner - No Wifi.

No BA Dreamliners currently have passenger wifi.

Did the 777 ex-LGW G-VIIX that came back from Singapore refurb get WiFi fitted? This would make sense but maybe not if it’s not done in SIN...

Was on BA117 last Friday to New York (744) and it has WiFi.

First hour was free if you register, no credit card details needed. Was actually impressed with the service.

Only five long haul heavies and not one short haul with WiFi? Whatever is the hold up? This is surely comically behind schedule.

Quite a lot of the short haul aircraft have actually been fitted, 2 Wi-Fi receivers on the bottom of the aircraft. The delay will be due to CAA radio licensing or the Wi-Fi ground towers that are set to be used.

It's important to reiterate that there are two different systems, one for long-haul, one for short-haul. BA themselves don't make that very clear. Both solutions are very new, and in my opinion it was the right decision to roll out something more future-proof which means it will actually be useful for something.

The short-haul Inmarsat/Deutsche Telekom network is just about getting ready for commercial use. BA didn't do themselves favours by not distinguishing between the long-haul network (ready, but very new and teething problems) and the short-haul network (not even quite ready yet), and especially for the latter there isn't really delays, but it was never going to be ready when announced to begin with. Also, for the long-haul network, there are still entire aircraft types (such as the 787) that don't have an antenna solution available from Gogo at all yet.

The shorthaul network won't be using Wifi ground towers, but cellular downstream over land, a bit like the original Gogo, with Satellite upstream, and Satellite downstream over the sea. I don't think the CAA has much to do with this now, as this is a pan-European network and the aircraft certifications will be done. Viasat is currently throwing its toys out of the pram because of that land-based component, but that legal challenge doesn't seem to have delayed things, and it should ensure that the bandwidth will be useable if this is picked up by more and more airlines.

So, short of BA rushing the announcements to combat Norwegian, I think this is all just as quick or slow as had to be expected...

There are more. G-STBL has it fitted (mentioned on Twitter on Feb 25th that it was fitted 'a few weeks ago').
CIVW, CIVY and a couple of the BYG's have had major maintenance recently which you'd assume would include wifi fitting.

The problem is that BA don't announce which planes have it until you're on board so you're relying on tweets, messages on here or hoping someone at BA Enginerring comes along with a list of aircraft that have it.
