Well, I wasn't concerned about the blankets provided on planes until I read some of the comments here!
I was all prepared for my RS tour in Ireland in early May, sandwiched between an early arrival in Dublin and a late departure from Belfast. Maybe next year.
Having lost a lot of weight, the new clothes I bought were specifically for that trip. My palette was olive and black with a camouflage twist.
The problem was planning for the weather. So I got 2 camo scarves. I can't wear wool and I like my scarves to be patterned.
This Fall Winter Travel Scarf was my first choice. It is definitely warmer than anything I normally wear. I love the colors. Unlike the instructions, I machine washed it on cold and dried it on low with a dryer sheet and it came out great. Whether or not blankets are provided by the time I finally get to go on that trip, it will work great for the cold plane.
The Amazon link is to a variety of scarves by the same company, Gerinly. The other one I got is much lighter, a different pattern and a slightly different size, even though the description is similar. This is it.
