Airport Lounges (again - sorry)

freccles

Without having to take out a new credit card or bank account, is there any way of getting any sort of reduction on airport lounges (specifically Manchester) please? TIA

Most agents charge the same, you may however find either promo codes or cash back offerings from certain agents. For example Holiday Extras do 6.4% cash back via Quidco for lounges.

Bear with me this might sound complex... (also I've not travelled recently so not tried this myself)

Dufry run most of the airport duty free stores and have a loyalty system.
What is RED BY DUFRY | Red By Dufry

As a member of that loyalty system you get discounts in the duty free stores, but also can sign up to get discounted lounge at $25 access via DragonPass.
See How does RED by Dufry loyalty scheme work? (headforpoints.com) 
Once you have the RED app you then find the DragonPass link and it takes you off to buy a pass on the DragonPass site.

So take a look at the regular price and what is offered and decide if you think its worth spending $25 (about £21) on a pass.
