Have just arrived home flying Qantas LYS-LHR-SIN-SYD. Husband and I in Business (first time ever and enjoyed every minute of it), 2 teenagers in Economy. Had a disappointing experience when trying to access the Lounge at LHR Terminal 3, which is the BA lounge. I knew that the conditions for entry are that you are allowed one guest with one Business passenger if on same flight, which we were ( I do alot of research prior to travelling). We were told no guests were allowed because it is a BA Lounge, but I had read on the Qantas website in their Lounge section, specifically this particular lounge, that the guest allowance applied. I actually pulled out my iPad and showed the Qantas supervisor at the Lounge the website information. She calmly stated the information was wrong, and they get problems all the time with passengers assuming the information is correct. She actually asked me to contact Qantas( gave me contact information) to make a complaint which I will be doing.
I suppose it is not that terrible a thing to happen, but lounge access for accompanying kids was a bonus I and the kids were looking forward to, especially being able to shower prior to the next leg of our long journey home. In the end hubby and I did stay in the Lounge to freshen up, and sent our teens out to find something to eat and drink for themselves.
My extreme annoyance is that you woud think a large corporation like Qantas surely could have correct information on their website, especially as it seems to have been brought to their staff's attention apparently many times previously. I just checked the website now, and that "incorrect" info is still there.
So be aware no guests allowed.
