United Airlines has blamed Boeing for a $200m (£161m) hit to its earnings in the first three months of this year.
The carrier was forced to ground its Boeing 737 MAX 9 fleet for three weeks after a mid-air cabin blowout on an Alaska Airlines flight in January.
United said that pushed it to a pre-tax loss of $164m for the first quarter.
Such bans, or rather groundings, are up to the FAA. So far, they actually let Boeing self-regulate. Maybe this will change that stance.
