My flight is scheduled on time, good to know as I only have only an hour in Atlanta:

Delta's check in zone:

I checked in with a very friendly agent who hands me over both my boarding passes for ATL and CDG. She tries to print out the last leg but can't. Then she realizes I have a train booking from CDG to BRU and apologizes she can't print it. She tells me I need to pick up my bags in CDG and go to the train station to obtain my train boarding pass. I know the process as I did choose it on purpose: my tickets are booked ex and to BRU as they are cheaper than from BSL. I will skip the last leg and take a flight to BSL instead.
Nice Christmas stuff:

Going upstairs to the D Gates:

I breezed through TSA, all agents were very nice and smiling. Christmas spirit may have helped. Then I board the train to the D concourse:

I loved this Star wars Christmas tree:

Gates are one floor up:

FIDS:

A bit of spotting with this 737-800 and this 767-300 to ATL a bit later in the morning:

AA A321:

717 to SLC:

The sun begins to rise:

Boarding is called on time, priorities are strictly enforced, as usual with DL. Very nice welcome from the F/As.
Here the cabin of this 757-300:

A few comments;
- The screens are pretty big and have a very good definition
- USB plugs are below to screens and power plugs between the seats
- Row 1AB has to be avoided, the pitch is awful as the bulkhead very near is
- Row 1CD is a bit better but still, there's more legroom in "regular" rows
- Recline is pretty good and the seat is comfortable enough
A welcome drink was offered. Coffee-baileys for me:

We took off on time, unfortunately no outside views, I had an aisle seat.
Nous partirons à l'heure, pas de photos extérieures, je n'étais pas à la fenêtre.
Safety card:

Once we reached the cruising altitude, the service began with a hot towel:

Today's meal choice are either cinnamon - passion fruit oatmeal or an omelet with provolone cheese together with chicken apple sausages. I took the latter:

It was a really good meal. The omelet was tasty and not overcooked, one of the best I had in a plane. The bagel came with Philadelphia cheese or butter/jam. The fruits were not top, however.
Service was very attentive and proactive. The lead FA made sure glasses were never empty and all requests fulfilled.
I managed to sleep a bit throughout the flight. We landed 20 minutes early in ATL.
A last picture of the cabin:

To conclude, some pictures from my room at the Cosmo in Vegas:
