From IAG press release:
"In late April, we completed our purchase of bmi. As a result, British Airways is able to manage its wider Heathrow slot portfolio more effectively and is launching a new route to Seoul later this year. Airports across the UK and beyond have contacted us about starting services and, subject to reaching satisfactory agreement with them, we plan to also launch flights from Heathrow to Leeds-Bradford, Rotterdam and Zagreb and increase frequencies to existing key destinations. Consultation continues with bmi mainlinestaff and their trade unions about plans to integrate the business into British Airways.
With BA at NCL and possibly LBA, prospect of a LON route looks more remote.
