Aircraft without problems that leave on time, not 2 hours late with last minute gate changes across the terminal

I like Delta. I dislike the volume of announcements from the crew. They are not always easy to hear and typically repetitive.

Sat in the plane at the gate in SLC for 2+ hours before take off, getting me home nearly 3 hours later than planned.

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

We never made it on this flight because we missed our connection due to o delayed flight from Jackson.

Average seat comfort, a drink and chips were provided, early boarding because we checked a carryon at the gate was nice. Ticket pricing shenanigans, including fees to pick a seat, check a bag, and get food onboard - evidence the industry is reinvigorating last century’s strategies- destroys the experience before one ever arrives at the airport. It’s difficult to recognize any value or sustain loyalty in the end-to-end process making air travel more drudgery than pleasure.

Everything was great until I lost my water bottle and they can’t seem to locate it. I know I left it on the plane though.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

Having to up charge for a seat assignment is not good. Delta can do better
