When passing through London Heathrow after an overnight flight from JFK, we spent a few hours in the SkyTeam Lounge in Terminal 4 before our connecting flight to Malta via Air Malta. We had a number of options through Priority Pass in selecting our London lounge, including a couple in Terminal 3 (where we landed), and multiple options in Terminal 4 (from where our Malta flight departed) – a branch of the Art & Lounge, a Plaza Premium Lounge, and the SkyTeam Lounge. We opted for the SkyTeam Lounge in Terminal 4 based on other online reviews, and we were not disappointed. The SkyTeam Lounge was a GREAT Priority Pass lounge! Side note – Heathrow is almost always a mess, so I always recommend lounging in your departure terminal rather than the arrival terminal and, more importantly, leaving LOTS of time between connections, especially coming from the US and then connecting elsewhere in Europe.
