If a passenger inconveniences an airline then the passenger is penalised.
For example, name changes, not checking in on time, cabin baggage too big or too heavy and cancellation has a fee attached.
You might say that this is fair enough because rules is rules.
On the other hand, if an airline inconveniences a passenger then similar penalties are not applied.
For example, flight times rescheduled by 11hours 59 minutes are not considered as major and therefore no compensation.
In this Monarch instance, I read that money for a service not given will be refunded but that should be an automatic response from the airline and not one which has to be applied for with the passenger having to be further inconvenienced.
Airlines get away with treating us like mugs and we keep giving them our custom .... me included, unfortunately.
Rant over.
