It should get you there and back (6,6)

I believe the answer is:

return ticket

(Other definitions for return ticket that I've seen before include "Permit for round trip" , "No single" , "homing device?" , "Two-way journey pass" , "Voucher for journey back" .)

I've seen this clue in The Guardian.
