Westcoaster,the fact that Arik uses european registered A340s to operate the LON route does not mean 5N A/C are not allowed to operate to Europe.It may interest you to know that even Arik sometimes operate the LON.route with 5N registered B737NG when the A340s are AOG. Bellview has always operated their LON flights with 5N registered B767. Finally,even though the ARIK A340s are portuguese registered,the pilots ,are from different countries, Nigeria inclusive.
