Depends which country and which airline, right, along with a whole pile of context.
Trust is earned. The airline industry has earned a lot of trust by having, amongst other things, extremely thorough accident investigations and extremely high safety standards. They also introduce new technology slowly and conservatively. People don't have to take the word of random 'experts' for this, because they can see with their own eyes that plane crashes are extremely rare. In the even rarer case where it's discovered to be due to genuine negligence or malign behaviour (see: Boeing 737 MAX fiasco), that is very widely discussed and executives are held to account via legal liability frameworks.
The COVID vaccine industry has not earned this trust:
1. Vaccine makers insist on blanket exemptions from legal liability of any kind in order to sell vaccines to a country, even if it is shown in a court that they were negligent. Check the leaked Pfizer contracts if you don't believe me. Governments have changed their laws in some cases to enable this (liability exemption pre-dates COVID).
2. People can see, with their own eyes, that vaccines have side effects they weren't told were possible. Now the law courts are forcing documents out of the FDA we can see that Pfizer knew about these side effects but didn't tell people about them (probably others too).
3. When something goes wrong and someone is injured by a vaccine, there is no crash-style investigation process. Instead it's swept under the rug, e.g. doctors will happily deny there's any connection between a vaccine and a severe reaction that happens just hours later.
And so on, and so on.
The problem with people who hate "anti-vaxxers" (they usually aren't actually anti-vaxx in general), is that they don't seem able to handle nuance or complexity. Even the derogatory label anti-vaxxer is like this, it strips all the complexity from people's positions. Comparisons between airlines (massively trusted, earned) and Pfizer (recipient of the biggest corporate fine in history, not massively trusted, earned) are in no way useful because not all institutions are the same.
