I finally splurged on Etihad Business Class using miles for my Abu Dhabi trip last year, and it was worth every point. At first, I tried booking online with my Etihad Guest miles, but I couldn’t figure out the availability — some days showed, others didn’t. I didn’t want to waste points on the wrong option, so I called 877-764-3622. The agent explained how to find the “saver” seats, compared mileage costs with cash upgrades, and secured my booking while I was on the line. Having someone guide me through made it stress-free, and the flight itself — lie-flat seat, great food, and lounge access — felt like a completely different travel experience. Later, I had to adjust my return flight, and the same number made the change easy. If you need to instantly book, cancel, or modify Etihad flights with miles, that’s the way to go.
