Wizz Air, a budget airline, is testing a new subscription model called WIZZ Multi-Pass in Europe for passengers on domestic routes in Italy and international routes to and from Poland. The six-month subscription pass, which must be paid for in six fixed monthly payments, allows travellers to take either a one-way or return trip each month. Subscribers will be able to select from four different plan options which include ticket only, ticket and WIZZ priority, ticket and a 20 kg checked bag, or the most substantial package, which includes all of the elements already mentioned. Subscribers will be able to purchase additional add-on services when booking a flight. Wizz is launching the subscription model in May.
