Both the Tube or bags work well. If I am traveling with only one pair I use the Tube. It has wheels and a pad lock.
With two pairs, I use a bag because a bag is lighter and easier to muscle into a car. I wrap my skis in newspaper before packing them into a bag so that they don't inflict damage on each other during transit.
Be prepared for your bag to pick up abrasions, grease and dirt from the baggage handdling process. Even a Tube is subject to dents at each end.
I've been transporting skis both ways for years. The only problems I've ever encountered is having my skis misdirected to the wrong destination from time to time
