If you have a Regus card (or a DragonPass, as they are usually accepted at airport locations), you’ll be interested to know that the new Regus Express business centre in Heathrow Terminal 3 I wrote about a few months ago is now open.
Unlike the Terminal 5 centre, which is in the Arrivals area, this one is in Departures. You need to go up the Terminal 3 escalators in Departures to the level where security is.
Instead of turning left towards security channel, turn right towards Pret. Regus Express is just around the corner. Whilst it is in the Departures area, it is BEFORE security so you don’t need a flight ticket to use it.
