Reply To: Negel vasser on an airplane

I used a water bottle. B”H I had two seats, aisle and window. After sleeping, I did not use the restroom. I sat in the windowseat.

Using a water bottle, I washed my fingertips (up to second knuckle from fingernails) three times, right then left then right and so forth, and the water fell off my hands onto napkins on the aisle seat tray table.

I did not say a bracha. For years I said a bracha but someone told me that it’s not allowed until after I use the restroom.

But am I supposed to wash then again negel vasser after the restroom?

One Shabbat, attended a shiur about Ashair Yatzar at the shul. The rabbi said that negel vasser is not required, ever. All that is required is to wash hands with water before saying Ashair Yatzar.

Also interesting spin-off: There is no time limit to saying Ashair Yatzar. Unlike eating where the after bracha is 70 minutes. If someone forgot to say Ashair Yatzar, hours or more ago, the bracha is still permitted.

Is this different? Do I say the Al Natislas Yadayim after the washing, without repeating the washing?

Is washing half my hands enough to purify myself of the Ruach Ra?

Thank you
