- Unlike AA, Google has enough cash on hand to cover expenses for close to a year
- Unlike AA, the service Google provides is not commoditized and highly profitable
- Google's market cap is 100x that of AA
- Unlike AA, Google's services are not highly susceptible to disruption by things like fossil fuel prices, terrorist attacks, politics and global pandemics
Advertising is actually one of the first things to be scaled back in an uncertain economy, and due to the way most of Google's advertising business is based on auction based pricing, if 1% of companies pull their ads, Google will lose more than 1% of revenue, since prices also fall, so there is an amplification effect.
Google is still in a much better position than AA though.
There's also more than revenue and profits.... AAL may also have had debt or a lack of spare cash; I couldn't find exact breakdowns but some articles suggest their buybacks caused negative free cash flow

Contrast with AAPL and GOOG who had, and have, tons of cash on hand. As of 2019, $102B and $117B respectively, which makes them them #2 and #1.
