Great overall experience and use of the Delta One lounge was amazing!

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

Chairs don’t recline and the ones that do recline, barely do recline. It was most uncomfortable flight i ever been on.

Everything was pretty good. I would like to have more drinks (water) during four hours of the flight.

Rude staff from baggage check to gate crew. Poor instructions. Inconsistent application of baggage rules.

Requested an aisle seat at the gate and got it. The staff so friendly

Had to deplane 2 x due to problems with plane. Delayed over 6 hours ans was given a $12 food credit which barely oaud for anything and limited to wear incoukd redeem.

I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska
