Sounds like good news, but the opening hours are a bit restrictive. I do a T1 to T1 Domestic every Friday, but will probably just miss the 6pm closing time.
A thought occured to me last Friday, usually the security queue at T1 Domestic is much shorter than the transfer security, so would it be possible to go landside on arrival and then just walk through to T1 Domestic departures? Would security allow this?
