New 737-900

[Devil's Advocate]

737s had the eybrow windows until the model 737-600 AFAIR. Starting from 737-700s those were gone.

The eyebrow windows were removed in 2005, about 8 years after the 737NG entered service. I think most of the NGs were probably retrofitted to remove them.

I remember reading that 737 aircraft delivered with eyebrow windows had never been certified for use without them and thus were ineligible to have them structurally removed after delivery. However, it's quite possible that a third party vendor managed to receive approval for removable non-structural plugs or filters for blocking excessive sunlight that could interfere with interior visibility.

Did some research. It was a plug, not an actual removal of the structure on planes built with them. Based on a press release from 2005 when the removal of the eyebrow was announced, the plug was developed by Boeing itself.

What about the DC-9's and its successor's, the MD-80's,90's and B-717's...IIRC, they had 'em, too...were they later discontinued and/or plugged?

The MD-80(?) that I flew on yesterday still had them.

MD-80's, 90's, do have the windows. The 717's seem to be a mixed bag. There's some Hawaiian Airlines 717's with the eyebrow windows. The Delta 717's (ex AirTran) don't have them.
