No. 1 Lounge at LHR Terminal 3
With batmandds arriving from FRA at the same time as my MUC flight, we met just before Terminal 2 Immigration and headed downstairs to the inter-terminal shuttle to Terminal 3.
OK, this is one ancient terminal. We re-cleared security and headed for the transit desk. Helpful SkyTeam agent contacted Garuda with our flight and passport info. A few minutes later, he advised us to go to the lounge where a Garuda rep would find us with our boarding passes.
Garuda uses the something called the No. 1 Lounge, which seems to be the main lounge for airlines with limited LHR service. Although not fancy, it's a rather pleasant Business Class facility, ith a number of smaller reserved rooms for First Class passengers. We found a good spot in one of those rooms to spend the next 4 hours. Staff was friendly and very helpful. Wifi was adequate and I was able to get some work done and then take a shower.
There was a limited selection of serve yourself food options in the main section of the lounge. In addition, we were offered a menu with made to order dishes.
Our spot in the First Class section of the lounge.
About a half hour after we arrived, a personable Garuda rep Luke stopped by and introduced himself, delivered our boarding passes and advised that he would be escorting us to the gate and plane.
