Once again, Lula seems to be trying to be all things to all people in this latest crisis - but with tempers running high, he may need to show more toughness if he wants to avoid further chaos in the air.
The European air traffic agency Eurocontrol said the ensuing chaos was worse on Friday than the previous day, and warned of "significant disruption" to air traffic on Saturday.
The travel chaos rippled across Europe as many airlines, including Air France, Alitalia, Lufthansa, Iberia and Aer Lingus canceled flights to Heathrow.
Strikes planned for the spring and summer by pilots at Delta Air Lines and flight attendants at American Airlines and United Airlines could still bring chaos for travellers.
Take the chaos that has engulfed Brazil's airports for the past six months, the result of a creaking air-traffic control system operated by disgruntled air-force staff.
