I'm traveling to the UK from the U.S. via Delta - coach class. Does anyone know if they provide pillows and blankets? If not, what would you recommend to assure a comfortable trip?

Bring your own. Based on coach travel within the US, you don't get either unless you are extremely lucky. Plan on not having them

Yes, you will get a pillow, blanket, headphones, wine (other alcohol is $).

coach travel in the US is VERY different from TATL. You will get a pillow, blanket and a meal but sometimes they don't load enough pillows and blankets for everyone.

Yes they are normally provided on transatlantic flights. For 'a comfortable trip' I would add your own earplugs or headphones, sleep eye mask, small bottle of face moisturizer cream.

You could pack your own travel pillow & small blanket if you want to be sure to have one. For me, because I pack very light, I have never bothered.

Thanks, everyone!

Flew Delta in August to Europe and back, and pillows and blankets were in all seats in coach. Also, wine was served with the main meal. I use a large scarf as blanket on flights, and also of course as an easy fashion accessory.

Beer and wine are complimentary in coach on Delta during the entire flight.
