Travel from Varanasi airport to Allahabad

Has anyone recently travelled from Varanasi airport to Prayagraj?

As I am traveling alone and the flight would land by 10.30 am, thinking to use public transport like bus or train rather than cab which would be costly.

I understand there is

1. Varanasi electric bus service from Babatpur airport to Cantt Railway station ( bus station is walkable distance),

Can some one who used this service share timings and fare details -

1. From cantt bus stand I can get the upsrtc bus

2. Are there shared cabs to allahabad directly from airport, if yes what's the price ?

Thanks in advance.
