With many of these types of things it is all in the detail
Before you pay, the info is in the Trip Summary, you can see 'Economy L' on this example which i have searched, filled in the passenger details, but not yet paid.
as has been mentioned, expect the lounges to be busy from around 23:30 until about 01:00 as people leave for the 2am batch of departures.
