I see no hate in the comments, except perhaps veiled in your use of the word. It seems your sense of privilege and entitlement is impinged.

High-level aeromobility is practiced by small minorities of the populations globally and of developed countries, but it causes a greatly disproportionate amount of the industry's emissions. Aviation consumes over 6% of global refinery production, its CO2 emissions are about 40% of those of the whole tourism industry, and it causes as much as 14% of all human-caused radiative forcing on the climate. Civil aviation is expected to grow at over 5% annually for the foreseeable future and to emit as much as 40% of the entire global CO2 budget by 2050. The latter does not include radiative forcing from other GHGs emitted at high altitude. (Higham et. al 2013, "Climate change, discretionary air travel, and the 'flyers' dilemma'").

You ask, "would you rather half empty planes fly?". Airlines would use smaller planes and/or fewer flights.
