We've had a marginal delay to some of the outbound and inbound flights. Two outbounds and three inbounds have been delayed.

A brand new flight route between Birmingham Airport and New York’s John F Kennedy Airport will launch next May, American Airlines have announced.
It is hoped that the launch, which will introduce direct daily flights to and from New York from 8 May 2015, will boost business and tourism links, encouraging new intercontinental relationships.
Last year, the West Midlands exported £4.5billion worth of goods to North America and has the largest trade surplus with North America of any UK region, and with global brands such as JLR, JCB, Cadbury and Kraft trading both locally and in the US, this is an important link for Midlands’ business.
The region is also a major tourist destination for Americans, with attractions such as Stratford, Warwick and Birmingham drawing in thousands of visitors every year so we look forward to welcoming many of these tourists into Birmingham next summer and thank the team at American Airlines for recognising the region’s vast market opportunities.
The new route is expected to provide just under 100,000 seats between Birmingham Airport and JFK.
Customers will also be entitled to earn and redeem British Airways air miles due to a code share between the two airlines.
As the seventh largest airport in the UK, Birmingham Airport currently handles more than nine million passengers.
Adding Birmingham to American’s growing global network is an exciting development.
Tourists from the U.S. will have closer access to a wide range of attractions in the Midlands while business travellers will also be rewarded with greater choice when flying across the Atlantic.

An investigation is underway at Birmingham Airport after a drunk passenger allegedly managed to breach security and board an empty plane.
It happened in the early hours of 17 July when Lee Jezard, from Redditch, allegedly made his way onto the airfield and boarded a passenger jet.
West Midlands Police said the 22-year-old was arrested at 1.10am and charged later that day with the offence of entering a security restricted area of an aerodrome without the permission of the manager and a separate offence of boarding an aircraft without permission.
He was released on bail, with conditions not to attend any airport in the UK, and is due to appear before Birmingham magistrates on August 20.
It is thought Jezard missed his flight to Ibiza the previous day and had been re-booked on a flight leaving the next day. He allegedly started drinking at an airport bar before getting airside.
An airport spokesman said: "An investigation is under way."
