772



This seatmap is being used for all flights will an sUA 777-200ER scheduled. It is being used to guard against equipment swaps into one of the three possible seating configurations: legacy sUA 3-class (8F/40J and 3-3-3 in Y), 2-class Polaris (50J and 3-4-3Y), and 3-class Polaris/PE (50J/24W and 3-4-3 Y). The actual seatmap for the aircraft assigned to your flight will become available when the flight is added to the normal Flight Status display, approximately 60 hours before departure (usually overnight).

Blocks in Economy are at all 'F' seats, plus 20CH, 21BJ, 22BJ, and 35ABCDE (the last for accommodation). The blocks are designed so that, regardless of which equipment flies, no one will be moved or scrambled when the seatmap updates. Instead, some seats will unblock and some blocked seats may be deleted based on the real configuration, and then some rows may be added. This process is similar to that for the 757-300, 737-900, and other frames with uncertain configurations.

Some danger remains if there are more equipment swaps after the initial frame assignment, and the change from F/J to Polaris in the forward cabins is not a well-defined mapping.

Premium Economy, if on the plane used, would be Rows 20-22, Seats AB[ ]DEFG[ ]KL

773


Similarly, as Premium Plus is added to the existing Polaris 773s, Rows 19/20/21 seats B & K are not shown, to accommodate potential swaps between PP & non-PP equipped aircraft.

It is speculated that once PP is offered as a true separate cabin. UA will focus the PP equipped aircraft on a few selected routes to minimize the swap risk.

I have been on 340 3 times in the last month, on 3 different configurations ( Premium Plus, old UA, and Domestic 3-4-3) and at least two of them had multiple plane swaps before the day of departure. So I would say you should have zero confidence that this plane will look like this in a month.

What amazes me about those swaps is the difference in the number of C seats between the domestic and the two into-configurations, that would seem to cause problems.

As a 1K do I have any hope of better reassigned seats in a swap, or is it a "computer assigns what's left" situation?

I've dealt with this swap multiple times in the past months.

If you sit near the front, you're more likely to keep your assigned seat. Status does not matter. It's "what's left" and basically "what matches" when the frame switches.

I've been on SFO-IAD multiple times when it switches from 60J to 48J (My numbers may be off; sorry). There are tons of upset people, literally tons. They find out at the gate. and start arguing why they're not seated in business and why they need to go to E+/E- middle seats. It's a horrible way to deal with it, puts all the pressure on the gate agents, when corporate could be calling people ahead of time. And of course SFO-IAD flights later are all booked full in business.

My advice? Sign up for text alerts. You'll get an alert very quickly when the frame switches and if you are aware, you can snag better seats each and every time (bulkhead E+, aisle J, window J, non across 4 J, literally every type of seat becomes available when the frame switches).

The standard swap is from Polaris to sUA 772s, which is a decrease of 2 J seats. They block those two seats from inventory until the gate, so a situation where the forward cabin is overbooked should be very rare. A 77G swap (48J to 28J) would do it, but I have almost never seen that on 340.

I lost my Premium Plus seat. And checked as soon as it switched.

Based on this thread and a strong suspicion that my GPU won't clear, I just moved myself from 28K to 22K on UA 106 (IAD-MUC) on June 14th. :fingers crossed:


ETA: The flight status for this flight currently indicates that we'll be on a 738 ... which would indeed be an impressive improvement in range for this aircraft. Is this standard for flights with this interim 77x seatmap? (EETA: Apparently, 738 is just a default, as I see it on every other instance.)

SFO-LHR chance of real polaris?

I'm flying UA 930 SFO-LHR on July 6 in biz and I have a slightly different seat map from the one in the wiki (see below). What are the chances that I end up with a swap to a real polaris product? Looking at the same flight in the next few days, it appears to still have the old config in biz.
