Is it possible to upgrade a seat to first class using miles after one has already upgraded to business class using miles?

AND!

Is it possible to get an OP-UPgrade at the gate to first class for a passenger who is flying in business class (upgraded from economy using miles)???

1-No, tried to do that at check in few weeks ago
2-Yes, but guess what, it happened to me right after I entered the lounge

1) Tried, but never worked for me
2) Happened on three occasions, twice at the gate. Once on a HKG>BKK>DXB flight, after we landed at HKG.

1. No. Miles can be used to upgrade to the next class. (not next, next class)
2. Yes

Without starting a new thread and the title is quite general here is my Q:

Upgrades with Miles at Check In-- how does it work-- How soon before departure? If there is a seat in (F in my case) the class avail (no an award seat) do they give it out then- or do you have to wait till the gate to be confirmed?

I wont bother turning up early if I cant get the seat on check in and use the F lounge-- will sleep an hour or so more at home instead!

the Flight I am going out on this week has 3 F seats avail at the moment- and never had any Z availability for past month for this flight.

Not sure if this helps, about 2 years ago, I was flying DXB-SYD EK419. Upon boarding the flight I noticed 2 vacant seats in J. I paid to upgrade the DXB-BKK leg
Anyhow; I complained later on for the treatment I received at BKK EK lounge.
In their reply, EK CS perhaps misunderstood my explanation and said:'

So to answer your question yyzlhr, I think the answer is no; (might as well sleep that hour ) And who knows, you might get op'd up because you got in late?!

Interesting-- but on board can be done regardless of what class is avail. an op-up doesnt look promising-- not full at all in Y and J appears to have at least 10 seats left-- but I am watching closely!

I allways wonder how this works. I fly regulalrly in F and J with Emirates for work and probably fly about 8 legs with them per month.

I used to ask for an upgrade with miles at Check-in as I have horded allot of miles and allways book in Y whenever I travel with the family which is Myself, the wife and 2 children, 1 of which is under 5.

In the past 18 months or so, I do ot use my miles anymore as every time and I mean every time I check-in, we are given complimentary upgrades and not just from Y to J but if there the aircraft is a 3 class configuration we have been from Y to F!! Once we flew from LHR - JNB and flew in F the whole way on discounted Y tickets.

I would like to know why and how they identify us for this, as I am not complaining, but friends of mine that fly with EK allways say they use miles to upgrade or very rarely get a comp upgrade. With the Nippy family it seems to be automatic!!

I have been a silver member and have been upgraded only once from economy to business. I have no idea how it works but in your case it maybe the case because you are a gold member and the flights you may have taken must be usually full.

With the new skywards program, i hope they dont make free upgrades more difficult.
