marlowe did you not comment on my wise words in my previous post ?
I do know the difference just if you read the article the headlines where the following :
"BA ready for growth take-off at city hub " and it says Willie Walsh wants his cityflyer operation at docklands airport to achieve profit margins of at least 10% . The number of flights is to be increased by 70% to 250 a week . So me think they might need more Aircraft .
