I just looked at those dates you said and it does say that some of the flights go via Glasgow - and if you choose the option to go this way on the outbound and the return leg then it is the most expensive ticket of the 4 options available.
For the dates I was looking at though - which was mid May to early June - none of them go via Glasgow.
What is scary though is the ticket price goes up by nearly £300 per adult for the July flights.
And there was me thinking prices might actually go down to encourage people to fly again.
