Personally I don’t think the Sport Options or Club offerings are too bad. Charter costs from the airlines are expensive, especially given the crew and plane usually stay in the destination until the flight back the following day/night, rather than flying off elsewhere.
Some people prefer direct flights, less time off work and less messing about with trains and connecting flights and are prepared to pay for that.
Others prefer to keep it cheap and can take longer off work, get trains etc.
Especially for Madrid, Leipzig, Dortmund etc where flights are limited from Manchester, I think Sport Options are competitive. For others like Barca, Paris, Lisbon etc, they’re less competitive and in those cases they tend not to offer a flight
