China Southern has 24, 737 Max 8 aircraft, with another 35 on order. China Eastern does not operate any 737 Max aircraft, but its China Eastern Yunnan subsidiary has four in storage, and its Shanghai Airlines subsidiary has 11 in storage. The Chinese carriers have joined other carriers such as Turkish Airlines and Flydubai in seeking out compensation from Boeing. On the 21st of May, Turkish Airlines chairman Ilker Ayci said that “compensation is on the table” in its discussions with Boeing.
Boeing has advised that it does not comment on its customer discussions.

Airlines for America predicts a whopping record 257.4 million passengers will fly on US airlines between the 1st of June and 31st of August while the Boeing 737 Max remains grounded. The MAX grounding took 200 daily flights out of service for the summer travel season. The group estimates the grounding results in a loss of 35,000 daily seats for the summer travel season. Airlines with 737 Max aircraft in storage are keeping passengers flying by rerouting flights and “lightly traveled routes” have been suspended, said US airlines chief economist John Heimlich on the 21st of May. If there is a prolonged grounding into late 2019 then airlines may pursue “deferring retirement of aircraft and acquiring used aircraft on the marketplace if needed”, Heimlich says.
