Business Class is a another thing, starting 355 days before departure.

Since when? I had to wait 100 days to select seats in J as of this Sep. for travel later this month.

This page confirms that policy. I don't know how long that has been.

I guess its no longer 100 days, these flights are about 180 days out, but weirdly the SEZ flights dont allow for seat selectionhttps://cimg9.ibsrv.net/gimg/www.fly...ae472fc053.jpg

Those SEZ flights show 332 aircraft. Is it 1-1-1 herringbone config leased from JET? Seat map is not showing online.

It seems that you can reserve seats more than 100 days out via the app. I booked a flight (December 2018) during the 15% off promo and selected my seats during the booking process:

I find seat selection on J bookings accessible beyond 100 days, but not on my Y bookings.

hmmm... or is it an ancient A332 with slanted seats.
Either way, not that there is any other choice on this route.

I booked VIE-IST-BOS-IAH TK Biz award yesterday via the UA site. I then went to the TK site to book seats. It would not recognize the PNR, even though it is the one given from the UA site FOR TK. So, Like I have done with OS and LO, I went to their Facebook page and messaged them requesting assistance. A prompt reply told me that I could chose my seats 100 days before departure. I reminded the agent that their website showed that J class seats can be chosen 355 days out, to which I received no reply. I went back to the TK site and reentered the PNR. It then asked me for the ticket number. I entered that and... voila! I was able to chose the seats. A330-300. I chose Row 4 center section. About thirty minutes later I got another Facebook message from TK saying they had been notified by the "TK Team" that our seats were now row 2, 2D and 2E, (or whatever the center section is.) Rows 3 and 4 still showed available but I left it at that. I just did NOT want to be row one. As long as we both have an aisle seat. I'm good.

I've also heard it's cooler toward the front of the plane so maybe row 2 will be better in that regard.

Dumb question, but what's the trick to change your seats?

I've previously selected seats, but now want to move. On the seat map page, I just see a red circle showing my current seat selection. Every time I try to select a new seat, I get this message "A passenger eligible for paid seat selection could not be found".

I assume this has something to do with the fact I've already selected my seats and the website won't let me unselect it...

Sorry...double pist.

So I booked a Biz seat for July during the sale this past fall. I booked via Priceline (I had reasons). When I looked up the res on the TK website, my seats were selected and it wouldn't allow my to change them. I posted here, and people said to wait until 100 days out.

Well, it's 100 days out, and NOW when I log into "manage reservations," I get a message "An unexpected problem occurred in your flights. Please review the flight details on your ticket." The itinerary shows up below it, but nothing is clickable or leads to anything else.

What gives?
