Really? Southwest carried over 41 million passengers in the first 6 months of this year, which equates to nearly 7 million per month. Interestingly the number of passengers enplaned in the period was over 47 million, or nearly 8 million a month. Given that they had 462 737s on the 30th June 2006, compared to Ryanair's 107 this isn't a great surprise!
