The magnetic pieces actually stay put, so nothing slid around on the tray table during our flight. My 4-year-old finished the sea picture twice and then started making up her own scenes with the extra pieces.

Bought this for a long car ride and it kept my 5-year-old busy for almost an hour, which never happens. The magnetic book format means no lost pieces rolling under the seats, though I wish the picture cards were a bit thicker since they bend easily.

The magnetic pieces stay put nicely on the pages, so my kid can play with it in the car without losing everything. The sea theme pictures are colorful and engaging, though I wish there were a few more puzzle options included for the price.
