About
Tiny Italian low-cost carrier MyAir's main hubs are Milan Orio al Serio, Venice, and Bologna. In all, MyAir flies to 17 destinations within Italy. The more unusual of these include Lampedusa and Pantelleria. MyAir flies to several airports otherwise underserved by budget airlines, including Lille, Metz-Nancy, and Santorini.

MyAir is a small player on the scene, though it is quite good for getting to Italian islands and regional French airports—in which case—it should definitely be your 'Air'.

Baggage
* Carry-on: One item, up to 7 kg.
* Checked: Up to two pieces of luggage, not to exceed 18 kg (€12 will be charged for each kg extra). The fee for checking in more than three pieces is €20 per piece. In addition, each checked bag is charged at the rate of €9. This fee doubles if you fail to pay on-line or at the time of booking and instead pay at the airport.
