The lounge offering does need a bit of a shake up.
As said, have a set of lounges dedicated to ‘pay as you go’ so that the masses can use them.
Then I’d personally look at having a ‘family lounge’. It can be quite a stressful experience bringing a family through the airport, and to me, MAN lacks a real family dedicated area where parents can relax as well as letting the kids play without p**sing off anyone else.
Then have the nice and quiet lounges, as well as ‘invitation only’ ones.
Also, I do wonder if the merits of an arrival lounge could help? Reported this week that business trips have increased by 55% in the North West for 2017, and there will be some that wouldmt mimd the chance to refresh and relax before continuing the day. The lounges at LHR seem to be well used....
