Shares in the low-cost airline Ryanair rose as much as 1.84% on 7 April 2015 in London after the company reported a surge in passenger numbers in March, compared to the same month in the previous year.

Ryanair reported that the number of passengers flying Ryanair rose 28% in the month, as it carried 6.7 million passengers in the month, up from 5.2 million passengers in the previous month.

The low-cost airline had gained notoriety for its uncompromising attitude towards its customers but its outspoken chief executive Michael O'Leary led a campaign to improve the relationship.

The company said the performance boost was down to its "Always Getting Better" campaign, which it launched in March 2014 in a bid to improve relations with customers.

The campaign "continues to deliver better than expected load factors on our significantly expanded winter schedule," said Ryanair chief marketing officer Kenny Jacobs.

"With our new routes, increased frequencies and Business Plus service, customers can now look forward to further service enhancements, as we roll out the second year of our AGB programme in 2015," said Mr Jacobs.

The firm's passenger flow has been increased by 9 million to a total of 90 million for the year, since March 2014.
