For those that travel I have about a two and half hour plane ride in about a week and half.. Wondering how you guys watch it on the plane

What kind of question is this? How do you watch anything on a plane?

Do you have a phone, a tablet, a laptop? Anything where you can locally download files and view them at your leisure?

Most planes allow you to pay for WiFi now anyways, and you could watch anime via any of the normal streaming services as long as you have a device capable of using one of these services (Phone, Tablet, Laptop, Nintendo Switch etc...).

Pay for WiFi and stream on your device, or download things in advance to your hard drive and watch them with a media player like VLC. Same watch you'd watch anything anywhere.... you're just on a plane.

I use my eyes.

Lold

I've also never been on a plane or traveled

See, that's a useful piece of information to provide. If you don't, you sound a bit special lol. Anyways, my post still stands and should help you watch anime on your trip.

Assuming flight information on the price of the WiFi is on there?

Just go to your airlines website.

You on the wrong airlines if wifi isn't free.
