Delta grounded their 62 A320s, for example, but continued to sell flights on their 31 A220-100 models and Swiss only operated 30% of their A320s but maintained flights on 45% of their 29 A220s. Between May and December 2020, airBaltic operated all its flights with its A220-300s to minimize complexity.
