lower fuel costs
shorter lines
everybody wins
The spot fuel cost may be lower, but the interest and capital payments on the planes continue. Most airline fuel is paid on long term contracts so no benefit there. The maintenance costs may diminish somewhat, but there are still maintenance costs. The airlines lease costs to the various municipalities continue unabated etc. so with no income coming in and outlays only somewhat diminished no joy there. The passengers who do fly risk getting a serious illness so no winners there. Rather than everybody wins everybody loses
