Can't seem to be able to check-in...... Not sure if this is a .bomb issue or weather related. Just might burn a 500-miler for this, it might be fun doing this short flight in the big bird.
That's cool. Just went to look into availability on a one-way trip on LAX-SFO today; On the "schedule & fare" results, aircraft for UA556 is shown as A320 and seat map is unavailable (though seat maps for earlier flights today were still available).
If it has the lie-flat seats, maybe you could have a 20-minute nap.
In my entire life, I've been on a 747 on a domestic flight only twice; once on NW in the early 90s MSP-LAX, and once in Dec 2008 on UA from ORD-SFO.
If you are on this flight today, I hope you'll post a report on it.
