1 interesting fact but may be not related to IR. Fact is that Lucknow is the city (I think so only city) which is having IR Code = LKO is just same as Airport Code = LKO (IATA Code). Interesting or not. If any other member knows any other city with same fact can share here. I am not including about another LJN station for this. If admins find not related to IR can delete it I don't have any issue.
