it should work if you configure the relation as IRRE relation with 
"foreign_field" set to "city". That's the only working way for a 
bidirectional relation without a intermediate table. Your current TCA 
setup would store the relations as CSV values in the field "travel", and 
that also only from side of the city. So just use IRRE for 
tx_..._model_city.travel and you're fine.
