After the training, go directly to travel at your own expense. Is the round-trip air ticket for training reimbursed?
Reimbursement According to the personal library network, the training arranged by the unit belongs to the work task, so the transportation expenses incurred during the business trip should be reimbursed by the unit. If the training arranged by the unit needs to arrive at the destination one day in advance, then the train ticket fee should also be reimbursed by the unit.
