Also, both this bus and the Lothian one, are dedicated to the airport trade with luggage racks. The tram is serving all local stops on the way, so is no faster than the bus, and no specific luggage room.
And the Lothian bus has integrated ticketing with the rest of the Lothian buses system- City, East Coast and West Lothian.
The new bus has integrated ticketing with the two Bright Bus Open Top tour routes. It's a bit early to tell yet if it is also within the ticketing scheme for the rest of the McGills network which includes buses to the Falkirk Wheel and the Kelpies.
It's a case where I know I should use the tram, but would a!ways the bus for convenience factor, personally.
I am a bit surprised to see competition on the route, and also that McGills can undercut Lothian's fares by £1.50, when they still have to pay the airport access charge. It feels as if the airport route will be cross subsidised by the open top routes.
