From another forum an EZY pilot flying from SEN states that headwinds and significant weather to go around en route are to blame, coupled with low wind speeds and higher temperatures on the deck. He took 3 hours to fly to Faro against headwinds of over 100 mph. If Runway 06 can be used the better climb performance helps, but that hasn't always been possible. At the moment the based aircraft have the lower TOW, an unfortunate result of the regular rotation of airframes.
