Flights being added on Manchester - Porto for the occasion:
British Airways (4)
EasyJet (4)
Ryanair (3)
TAP Air Portugal (1)
Transavia Holland (2) - These are believed to be charters?
Titan Airways (1) - for MCFC, not fans.
All subject to change, but check them out!
Note: Etihad Airways highly unlikely be involved in flying fans over from the UK. They are a non-EU carrier with no traffic rights to fly between Manchester-Porto. If they chose to use the PR to fly the team over in A6-BND (MCFC livery B787), they would likely be granted permission for that. Though it looks like the team will use Titan Airways at the moment.
