I am a US citizen visiting Indian on business. I have never flown on Aloha (I flew Hawaiian when I was there last) and have never flown a 737 next generation with winglets.
However, I just flew Jet Airways from Chennai (Madras) to New Delhi on a Boeing 737-700 with winglets. Although it was painted in Jet Airways's livery, I was pleasantly surprised to note the Aloha Airlines symbol on the first class seatbacks and that all of the seats were in grey leather (I assume an aloha touch).
Jet Airways' magazine notes one of their 13 737-700 has a slightly wider wingspan. I assume that is the wingletted Aloha plane.
Is Jet Airways leasing this aircraft or was it sold outright?
