Escape Lounge in T1 is still bookable from T1 in December on the MAN Airport website. That might be an indication it's staying for now, but 1903 Lounge is also still listed after then indicating that changes are yet to be updated.With confirmation (although not official) from the airport’s flights section page on the website, suggests Ryanair will be T1 based from 21st October for departures and T3 for arrivals.
But does MAG have a plan for their current T1 lounges, given the fact there aren’t any in T3.
I have a few Ryanair flights booked between October and January and would ideally like to book the Escape or Aspire lounge.
I recall CCGE29 mentioning Pier B will remain open for Ryanair from November (which you're probably aware of). Whether this is still the plan I'm not sure, but if so I'm assuming it will be around the date EasyJet move out. So before then I'm guessing it should be fine to access the current T1 Escape Lounge providing you have time to get back into the T3 departure lounge? After then I'm not sure, but I'm sure they'll be demand for one regardless (Liverpool which mostly has LCC's have just reopened and relocated their Aspire Lounge).
