Everyone is assuming that airlines like BA and Easy will weather this and the reality is that the outcome for any airline is far from certain. Until we know what/if quarantine requirements are for arrivals into countries, what the social distancing requirements will be for each country, what the pre-boarding/arrivals testing environment and timescales look like as things gear up, all this is far from certain. Fares will HAVE to rise (by a factor of at least 2 and more likely 3). The airline environment is set to change seismically from what it was pre-pandemic.
