Appreciate any insights on KE vs DL on ICN-SFO. I have a return flight in early June with option on DL codeshare on KE ICN-SFO (777) vs. true DL ICN-NRT-SFO (767). I prefer to stay on DL whenever possible. I've never flown KE. Is KE offering additional coach legroom for add-on like DL and KLM?
Thanks for your thoughts.
