USA and Canadian carriers wrestled with customer calls and flight cancellations and Southwest Airlines Co and American Airlines Group Inc, the largest US operators of the 737 MAX, said they had started flying empty MAX aircraft to be parked elsewhere during the ban.
According to estimates from the IBA Group, the direct costs to airlines for suspending the MAX would be around $150,000 per day per leased aircraft grounded.

The US Federal Aviation Administration (FAA) ordered the temporary grounding of all 737 MAX aircraft operated by US airlines or in US airspace on Wednesday.
Yesterday the FAA said 737 Max airliners would not be allowed to fly until new software had been "tested, approved and installed", a process likely to last until May, according to United States politicians briefed on the situation.
On Wednesday, US authorities said new evidence showed similarities between the Ethiopia crash and that of a Lion Air flight in Indonesia in October that claimed the lives of 189 people.
"There is no capacity here so the black box will be sent elsewhere for analysis".
The Federal Aviation Administration said findings from the crash site near Addis and "newly refined satellite data" warranted "further investigation of the possibility of a shared cause for the two incidents".
Airlines say they are working to rebook customers on other planes. He also noted that investigators have not yet drawn a clear link between the system that malfunctioned prior to the Lion Air crash and the Ethiopia accident.
The FAA's directive on Monday said that Boeing is updating the maneuvering system software, meaning that the system still poses potential flight risks.
U.S. Representative Rick Larsen said after a briefing with U.S. aviation officials the software upgrade would take a few weeks to complete, and installing it on all aircraft would take "at least through April".
Questions about the Lion Air crash have honed in on an automated stall prevention system, the MCAS, created to automatically point the plane's nose downwards if it is in danger of stalling.
In addition to Lion Air's alleged split from Boeing, several other companies are reconsidering their own ties with the American company.
Ethiopian Airlines CEO Tewolde GebreMariam said Sunday the flight's captain Yared Mulugeta Getachew, 29, was an experienced aviator with more than 8,000 flight hours.
The Ethiopian Airlines plane was less than four months old when it went down six minutes into its flight to Nairobi.
