Wizz expansion is welcome for Coventry, however that is better dealt with one thinks on the Coventry thread.
You might find that WIZZ like to fly from airports for next to nothing hence the absence from BHX.
As to the Polish in Birmingham only have to visit the city or any service idustry to see that there are a great number in the area.
I think that on the regional Polish flights that the cost of the ticket is everything.
