I love my 14-24mm but not for travel by air. Too big, too heavy, too conspicuous.
For several years I've been using my D800 and 17-35mm 2.8. No VR and 20th century optic sort-of designed for the D1, but still a pretty good lens for my needs. It's a little shorter than the 16-35mm and almost as wide, but a stop faster, something I need in ancient, dark, candle-lit monasteries. The image quality is fine for much of my work for print and publication.
However on this trip, I've downsized and left my D800s and the heavy glass back in California. I'm using a Panasonic 7-14mm on both my GX7 and for high-res, an Olympus EM-5, Mk. II. The IQ is nearly the same using the sensor-shift high-res mode as the D800/17-35mm.
But the weight and size is so much better. The Nikon kit weighs in at 19 kg. The Panasonic/Olympus comes in 5 kg and 2/3rds the size. I love the low-light ability of the D800 and fast lenses but my aging body really loves the size/weight of the m43 and small, sharp lenses!
