Not that there are many DL people from IAH, but I see availability in June and July on ita. Delta.dumb isn't working but there are other friendly places that you can go to get $591 a/i. Nice find, cfwolfs!
I actually have to give credit to AFWD. But I did all the CPM calculations myself!
Oh, and as AFWD reported, it's available from a whole bunch of cities throughout the US for under $600. If you're not following them on twitter or facebook, you should so you can post stuff like this!
It looks like the clincher is the city you want to fly from has to have non-stop service to either Detroit or Los Angeles, and the price remains under $600. I tried ALB, STL, TVC, GRR, CLE, FLL, PBI, SMF, PHX and all remained below $600.
Even a small amount of love for SEA and PDX on 3 or 4 days in June with codeshares on AS to LAX.
For Chicago people, this is working ex-MKE.
It's working out of the CHI airports too, but you have to stay 2 nights? Worked for a similar itin to the DTW-HND one I showed up above for 17-20, except it tacked on a ORD flight before and after. Leave at 3pmish on Friday, Home by 8amish on 20th
Fare seems to be good from just about everywhere in the USA to Haneda through July. I don't think it's a mistake fare. Obviously, travel to Tokyo has taken a huge hit due to the earthquake/tsunami/radiation problems, and DL is unloading unsold inventory.
Not really interested in visiting Japan right now -- it's more about the value of the yen than the radiation stuff. I presume there are still no really cheap fares ex-Tokyo for other (cheaper) Asian destinations?
