Norwegian Air - Food Questions

On the Norwegian website you can see illustrations of the menu with prices. I believe you can order ahead for longer international flights. Some airlines now will only accept plastic in payment during flights, no cash.

Thank you!!

We usually just picnic for food on Norwegian Air Shuttle. We carry stainless steel drink bottles on our trips now, and we buy iced tea flavor packets at Walmart. After going thru airport security, we will get water out of a water fountain. They save us substantially on our trips and flights.

Ditto.
Bring your own food;
you can find fresher and healthier stuff than anything an airline would sell you.
And by a bottle of something to bring on board to drink after security

I've flown Norwegian frequently - I like them.
Oslo to LA, LA to Paris, Oakland to Barcelona, London to Seattle....a good experience every time.
I upgrade to the "extra luggage / food / seat selection" option even though two of those three I don't need. But, at 6'6", the exit row seat selection is always desired, and I'm willing to pay for it - and scarf down their food when placed under my chin - I've had worse.
Those Dreamliners are nice and their flight attendants are very good.
Enjoy your flight!

Bring your own if possible the prices are nearly the same as the flight itself.

The answer to your question is yes, but I would supplement it by bringing my own food on. You can order snacks, etc from your seat on the TV screen in front of you, and it will be delivered to you. But in order to keep costs down, they don't bring on huge amounts of everything so would suggest ordering things you might want early in the flight. Have had one of their sandwiches before and it was just fine, nothing special.

Thank you for all your help! It's appreciated!
