Ryanair planes were carrying 'sufficient fuel' On July 26, the planes, which were bound for Madrid, were diverted to Valencia, but drew near to their minimum legal level of fuel. In its preliminary report, which followed a meeting with Spanish aviation authorities in Dublin, the IAA found that they departed with fuel in excess of legal requirements. IALPA, the Irish pilots" union, alleged that the airline put pressure on flight crews to carry the minimum amount of fuel required, in an attempt to cut costs. Ryanair has rejected the claims. Two more incidents involving the no-frills carrier last weekend are also being investigated. On Sunday, a flight from Paris to Tenerife was diverted to Madrid due to a technical issue, and on Saturday, a Ryanair flight was diverted to El Prat airport in Barcelona because of an engine fault.
