Purchased aircraft never arrived

It's a bug - I've put a "new" used aircraft in your fleet (#54640) equivalent to the one you bought.

Thanx

Hi there, I just had the same problem with a leased used aircraft. The money for the lease left the account+ under active leases is says the correct amount of leased aircraft. However I cant seem to find my aircraft.... Thx for the help

Which airline and aircraft did you have this problem with?

Hi,

This happened again now. Aircraft #10100 never arrived....

Hi,

 

This happened again now. Aircraft #10100 never arrived....

It's redelivered as #76264.

I've had this problem 3 times today, one 763ER, one 752 and one 733. The only aircraft details I have are for the 733 which is ID: 27073 in RD. 

Maybe there's no check for whether the plane is already bought/leased when player clicked on "Buy Aircraft" in the confirmation page?  Since that page is taking aloooot of time to load for me and there is a gap of up to a minute before actual purchase, and that seems to be causing alot of problems

And this is from my mail box:

Aircraft #14963 and #66509 was purchased by FlyWest (id: 1994 in rd) but never recieved.

I've had this problem 3 times today, one 763ER, one 752 and one 733. The only aircraft details I have are for the 733 which is ID: 27073 in RD. 

Looking at my newly-purchased aircrafts, the 763ER should be #6922 and the 752 should be #16638

Sorry for that

I have the same problem with 3 leased aircrafts:

aircraft ID: 47351 B737-400

aircraft ID: 49830 B737-400

aircraft ID: 71554 A320-200

Screenshots of the planedetails see:

http://www.airline-e...appeares-again/

Please help me.

I'm able to reproduce this issue by:
 
1. Airlines A purchase an aircraft, but leave it at the confirmation page
2. Airlines B purchase/lease the same aircraft and complete the transaction
3. Airlines A then click on "purchase aircraft"
 
In this case, B will have the money deducted for the purchase and briefly own the aircraft after step 2.  However, after step 3, A will take over the ownership of the aircraft.  The amount of time doesn't seems to matter too.  A can still take over B's aircraft even after 2 AE days has passed, as long as the confirmation page still opens.
 
Tried the same with A leasing, but it seems to be harder to reproduce.

I found out that I will have to pay the lease for the three planes that I leased, but nerver recieved.

(See screenshot)

Please remove or replace them.

So I spent a whole day looking at this, and there are all the aircrafts with double-ownership with the 3 scenarios I found that involves my airlines:

Unfortunately, there doesn't seems to be an easy way to filter out the cases for double-lease, double-buy, or leasing an aircraft bought by me, which I expect there should be many many more than the ones listed here.

Element Airways may want their aircraft back... That's a whole batch of 772s

This bug is now fixed, which should prevent the vast majority of these cases going forward. If an aircraft you are buying has been taken off the market after you loaded the confirmation page, that aircraft will be skipped when you confirm the purchase.

The issue is still apparent in my airline as with the 752 I had enough time to set up a BHX-EWR flight which "apparently" is being operated by Snowy Pacific under my prices, taking my slots and in my aircraft configuration. I do not receive any profit for this but seem to have paid all the costs, is there any way of amending this.

As you can see, I only operate one flight from EWR but its taken up 14 slots and not 7, with Snowy Pacifics "dual leased" 752 taking up the 7 extra slots, which is revenue for my airline.

Thanks

I never normally like to double post but had the issue again today with 733: ID: 19117 which was after I configured it to European Seating Arrangement of 6C 134Y 

Still hasn't arrived, doesn't seem to happen with my ATR-72 Aircraft I lease but happens with any Boeing Aircraft within Buy Used

Best Wishes

It happends with all Boeing and Airbus planes that I leased recently. Once again just now, see: http://www.airline-e...appeares-again/. -> plane ID 64574 (Airbus A319-100).

It is strange, but somehow Snowy Pacific is involved in all my disappearing planes. If you follow the used aircraft market and look at the details of the Airbus and Boeing planes that are offered you will see that most (almost all) of these planes get bought by Snowy Pacific within less than a minute no matter what time of the day/night it is.

I have now 10 airplanes that haven't arrived... #72776, #73716, #74179, #74671, #75124, #75553, #3219, #3505, #3780, #4092. As mentioned from someone else, it has only happened with Boeing and Airbus. Could you please deliver them to me as soon as possible?

Snowy Pacific airline is too big that why...

Most of them are from the same batch:

You have purchased the following aircraft for $617,901,480 (inl. commision):

    Aircraft ID #72776: Boeing 767-200ER (Age: 2 years, Value: $98,079,600.00)
    Aircraft ID #73716: Boeing 767-200ER (Age: 2 years, Value: $98,079,600.00)
    Aircraft ID #74179: Boeing 767-200ER (Age: 2 years, Value: $98,079,600.00)
    Aircraft ID #74671: Boeing 767-200ER (Age: 2 years, Value: $98,079,600.00)
    Aircraft ID #75124: Boeing 767-200ER (Age: 2 years, Value: $98,079,600.00)
    Aircraft ID #75553: Boeing 767-200ER (Age: 1 years, Value: $98,079,600.00)

Seems like the remaining issue is dealing with concurrent database execution. For some reason, airlines with large amount of aircrafts will take alot of time to load almost every page, so this is probably what happened:

1. Large airline load the confirmation page and confirm the purchase

2. AE performs check Yuxi just added for the large airline - yes, the aircraft is still on the market

3. Small airline load the confirmation page and confirm the purchase

4. AE performs check - yes, the aircraft is still on the market

5. Small airline process quickly and complete the purchase, taking the aircraft off market

6. Large airline finally done processing and complete the purchase assuming the aircraft is still on market

So small airline bought/lease the aircraft in step 5, but large airline take it over at step 6.

Now the question is, why it takes so long for large airlines to buy used aircraft - how would the amount of planes affect the purchase of aircraft and what is AE actually doing beside changing owner/operator, deducting money, etc

Currently it takes 1m15s to purchase a used aircraft for Snowy Pacific or probably any airlines with 20k aircrafts, whereas a new airline can generally finish in less than 10s.

I think AE should really use database transaction for situation like this.  Something similar to:

BEGIN TRANSACTION
  <check query>
  ...
  <purchase query>
COMMIT TRANSACTION

In this case airlines would wait in a queue to make sure only one airline is purchasing at a time.  I know this will be slower, but at least everyone will get the correct plane...

Better yet, I wonder if there's a way to make the check and purchase into a single database query, maybe something like

// commit purchase first on only the aircraft on market
UPDATE aircraft SET ...... WHERE operator = "";
// get a list of aircraft actually purchased to deduct money and do everything else
SELECT * FROM aircraft ...... WHERE operator = <buyer> AND id IN (<list of aircraft id from req>);
INSERT INTO aircraft_history ......

Just two suggestions that may fix this issue...
