Manchester inbound vs Birmingham
Mancheter has one of the globes largest brands not only bringing tourists to the city for games, but most importantly keeping the city on the global stage in terms of consumer awareness.
Consumers in growing world markets don't think about Birmingham as a place they want to visit. They hardly understand that Villa, West Brom etc are near to this city.
They all know of Man Utd, starting to know about Man City and ironically also all know of Liverpool.
Airlines like Air Asia X are all about serving rapidly growing disposable incomes in Malaysia where these consumers want to shop in Europe. Especially in places their friends have heard of. This is a reason why markets in South East Asia have huge potential for inbound tourism.
