Havent flown by Etihad yet.

I am considering the following itin with a 45 min connection time at GVA, all on one ticket through expedia

OPO->GVA (arrival 1030)
GVA->AUH
AUH->BLR

Airline: Etihad, check-in at OPO at TAP airlines (codeshared with Etihad).

This is very tight, how inadvisable is this?

Will the luggage be checked through to BLR?

If I miss the GVA connection, I do not mind being rebooked on a different flight
