A practical way to think about it is to remember that each ranking usually emphasizes certain metrics: punctuality, cabin comfort, loyalty benefits, or complaint volume. Referencing best and worst airlines when asking for clarification helps point directly to comparative data based on customer reviews. From there, it becomes easier to see that an airline can improve in one area while lagging in another, or perform well on particular routes but struggle in crowded hubs. Looking at a mix of recent ratings, personal priorities, and the specific cities involved gives a clearer picture than relying on a single league table, reducing frustration when rankings appear to jump around.
