Well, for 20-year-old Isabella Cruise, a private jet is obviously not necessary to fly the friendly skies.
In fact, when it came to heading over to Italy with friends this week, the gal opted to simply go commercial by way of budget airline Ryanair, as this Instagram photo she posted shows.
Sure, half-sister Suri Cruise might be accustomed to getting from point A to point B a bit more lavishly, but clearly Isabella can do without. (Although, in Suri's defense, she is only 7 and doesn't really have much say in the matter.)
During her time in Italy, Isabella has enjoyed dining in Tuscany and swimming in Florence.
Still sounds like a first-class vacation to us. Regardless of how she got there!
