Delta Comfort+

To me it's worth the cost. There is extra leg room and in most of the planes I've been in there is one less seat across. I usually go for the middle section, aisle seat. Economy comfort is usually 3 in the center whereas Basic is 4 in the center. No leg rests as there is not quite enough room for that. There is supposedly dedicated overhead bin space as well. If you don't have FF status you do get to board earlier.

I did the Superior on the way home from Amsterdam in May and did not think that was worth the cost. There was extra room BUT the tray tables for each seat (not just bulkhead) were in the arm rests so that meant you could not raise them to get out of the aisle seat. Plus the person in front of me reclined fully the instant he could and even with extra room that was uncomfortable.

We booked delta comfort+ to Spain for October. We like to have the 2 seat row and the extra leg room. On other airlines where we booked the higher option, we received better food choices. Also, when we missed a connecting flight in Frankfurt on Lufthansa we were the only people around us on the rebooking line who received an email with a new flight. They then changed the rebooking sign to hotel vouchers only. The other people we were talking to had to return the next morning to wait on the rebooking line again. We had upgraded on that flight too. They assured us our luggage would be on the plane too and it was (we were returning home). We will always upgrade in the future to what our budget allows.

It depends on how much the extra cost is. And how long your flight is.

A bit of additional comfort for a six- to ten-hour flight is worth the extra cost, yes.

I prefer the 2-seat configuration in Delta's Premium Economy on the A350 and will gladly spend to get it. Even the 2 leftmost or 2 rightmost in the 4 seat section of Premium Economy are fine. My partner is more likely to agree to travel if we can accommodate his tall frame. Unfortunately in the event of flight cancellations or change to another plane you still might get downgraded. I'm not sure how successful one might be if they pursued a refund of the cost difference.

Delta Comfort is definitely better than Main Cabin, however, if I can grab an exit seat in Main, I find those seats to be just as good, if not better, than Comfort Plus (leg room far superior on most layouts).

I recently watched a YouTube video about this and from what I could tell it was exactly like main cabin except a little more leg room. No leg rests. Not worth it for me. I suggest searching on YouTube as there are people out there filming the inside of specific planes to give you an exact idea of what the seats are like.

It depends on the price, and which direction I'm going but it is nice to have the extra leg room. For my upcoming Europe trip, I used miles to get bumped to Comfort.

When I went to Germany back in April, I used miles to bump up to Premium Select. In both cases, the miles I needed were reasonable (and the cost was, too, if I wanted to use $).

If the cost seems high, you might wait a bit - if you keep checking on the app, Delta will keep pushing the upgrades and the prices/miles will change from time to time.

Delta Comfort+ and main cabin are both arranged in 2-4-2 configuration for A330-200/A330-300/A330-900neo; 3-3-3 configuration for A350-900. Both have the same type of seat and seat width; Comfort+ has 3" more legroom than main cabin.

What I like about Comfort+ is not feeling like the seat in front of me is in my face. Those 3-4” make a difference. I’m short, 5’4”, so for me it’s not as much about leg room as it is about this. The last time I flew coach I couldn’t watch the screen (in the back of the seat) in front of me without feeling sick because it was so close. I’m done with coach!

I typically choose Comfort + when flying to Europe. Extra legroom, earlier boarding so I can get space above me in overhead bins, and while I'm not a drinker, freeze liquor. Somebody ALWAYS gets a souvenir from me after these flights.

Food arrives earlier, too

Here is the Delta blurb about 'Comfort+' ( one of 6 classes of seats; keeping the nomenclature straight is a task )

If you like to feel more rested following an international flight, absolutely. There are many other reasons as mentioned above, but it's nice to have two seats together and no middle seat.
