Hear it in context
Notice where the phrase sounds natural.
A return to Oxford, please.
A: Next, please!
B: A return to Oxford, please.
Fix the pattern
One small grammar move makes it sound right.
Not: One ticket go and back to Oxford.
Say: A return to Oxford, please.
'A return' = round trip; 'a single' = one-way. (US English: 'round-trip' / 'one-way'.)
