Very nicely written article, which I'm sure I will refer to multiple times over the next few years.
I did a RTW in Business using 280k KF last year which spoilt me but this year I'm putting together a RTW with a mish-mash of paid economy and reward Premium/Biz. Most of my travel in the last 15 years has been in economy, and mostly LCCs between MEL and Asia.
My first sector for 2024 is MEL-xCAN-FCO which I found in July for $605 in economy one-way. Flying halfway around the world for that price, on the day I wanted was nice.
Never flown China Southern before, but apparently this is 787-9 Dreamliner with 32" pitch, 9 abreast. More research shows this is 16.3-17.3" in width (why the variance! how can I choose?!).
Unfortunately it would be 2x $169 if I want to upgrade to the exit/bulkhead which is a bit much. At least I have 6 hours to stretch my legs halfway. Haven't flown this long in economy in one day since I took a Qantas A380 from JFK-xLAX-MEL about 15 years ago.
I've flown enough time on LCC like AirAsia, Cebu, Scoot that I simply cannot fly with them unless I book an exit row so I just calculate that into the price. But then again, with the tray table in the armrest, you are sacrificing width for length, so you cannot really win. A few times I've had a nightmare bulkhead door blocking my legroom and another memorable time in AirAsia, the passengers would keep walking across my legs to use the bathroom on the other side. Never book a bulkhead seat in the middle on a LCC!
You touched on width in the article, but I found an article that goes into even more interesting detail:
Those confusing aircraft seat measurements, explained - Runway Girl
I definitely feel there is a lack of detailed info on width. From the article
“We have standards for pitch, but width is the new pitch and it’s the Wild West out there right now,”
I feel that the worst part of flying economy is the skin to skin, shoulder to shoulder contact with other passengers. That article also say that 17" shoulders
"is an extra small according to clothier Brooks Brothers’ sizing chart. To be blunt, how many people wear an extra small?"
So even paying $169 per segment for extra legroom won't really solve my main problem.
I found a chart on longhaul economy seat width here:
Long-haul Economy Class Comparison Charti - SeatGuru
This explains a lot, Asian LCCs are 16.5" - no wonder I hate their seats but love their prices. I'm so used to flying to Asia in them now.... but going to Europe is going to be a struggle. In 2025 I'll be on another Star Alliance RTW, thank god!
