I have to say I agree. I flew about 8 DL F sectors mid last year and was pretty impressed with the service and attentiveness of the staff. AA wasn't bad, but DL were surprising, given everything that I'd heard about them to the negative. I haven't compared them to VX F but value for money wise I couldn't fault them.
I flew Delta in J LAX-SJO-LAX-SFO-LAX last month - the LAX <-> SJO legs were on a 757 and LAX <-> SFO on a 737 (from memory).
Delta were significantly cheaper in economy for my specific itinerary - on top of this, I was travelling with 2 check-in bags for an extended diving trip, and while booking, it quickly became clear that it was a no-brainer to fly in J as the baggage charges in Y meant that the incremental cost for J for the whole itinerary was only approx. US$300 (check-in bags were free for J). I reckon I flew in J for close to or less than any other airline was charging for economy, and the "check the cost for J including baggage" would be my top tip for others who are looking at booking flights with DL (or any other US airline, for that matter).
The lounges in LAX and SFO (no lounge in SJO) were a pleasant surprise, with plenty of space + snacks + free "standard" alcohol, along with the opportunity to pay for "premium" wines and spirits. Would rate them on a par with VA lounges in Oz and not too far below Qantas (driven primarily by the more limited food selection)
Seats on the plane were ho hum - for all the flights, they were similar to QF / VA domestic 737 J seats, which was more than fine for the short LAX-SFO-LAX legs, but disappointing (to say the least) for an overnight 5+ hour flight to Costa Rica.
In-flight food and service - generally tolerable (but no more than that), with the exception of the spectacularly surly chief stewardess for SJO - LAX. Not sure if she was having a bad day, or it was just her normal modus operandi (she was French
). I should have complained, but didn't have time while in LAX / SFO, and then CBA kicked in once I got back to Oz........
Would I fly with Delta again? Yes........
Were they value for money for the flights I needed? Absolutely......
