The US had snow in the winter to "explain" why for the second year in a row Q1 GDP tumbled from 3% to around 0%; Europe, whose GDP unlike its market (the Stoxx 600 just hit a record high) will also miss lofty expectations for an economic recovery thanks to ECB money printing, may have a French air traffic controllers strike to blame the Q2 GDP miss for.
Yesterday, the SNCTA union - France's largest - called the two-day strike in a dispute over working conditions. As BBC reports, later on Wednesday, the DGAC civil aviation authority asked airlines to halve scheduled flights on Thursday.
The immediate result: hundreds of flights and thousands of passengers have been grounded.
Short-haul flights have been the worst affected but France's largest airline, Air France, said long-haul flights were still operating.
The airline added that 60% of medium-haul flights from and to Paris' main airport, Charles de Gaulle, would still operate, but that it would ground two out of three flights at Paris' second-largest airport, Orly.
"Disruption is expected over the whole country," the DGAC said in a statement. Travellers have been advised to contact their airline.
What is the reason for the strike: France's civil aviation agency said part of the dispute involves plans to raise the retirement age for controllers from 57 to 59 years.
Further strikes are planned for 16 to 18 April and 29 April to 2 May, coinciding with spring school holidays in France.
Low-cost airline Ryanair says it has had to cancel more than 250 flights, with further cancellations likely, while competitor Easyjet has been forced to cancel 118 flight.
"We sincerely apologise to all customers affected by this unwarranted strike action and we call on the EU and French authorities to take measures to prevent any further disruption," said Ryanair in a statement.
"It's grossly unfair that thousands of European travellers will once again have their travel plans disrupted by the selfish actions of a tiny number of French ATC [air traffic control] workers."
Travellers booked on short and medium-haul Air France flights on Wednesday or Thursday can choose to travel between 10 and 15 April instead, it said.
The most notable outcome, is that the skies over France are rapidly becoming comparable to those over east Ukraine.
