libhomeradar - easy collect aircraft information - Details for the selected database entry
Per libhomeradar if you were on ZB248 then G-EOMA A332.
If this link shows blank then go to the homepage and tick the more than 30 day box, under call-sign use MON248 (not ZB) and select 500 or 1000 entries per page and hit search and you should get the result you want.
If you were on a charter flight just add the flight number MONxxxx in the call-sign box as per above.
However as this one shows 9/4/12 I assume this was your flight.
BHX
It seems BHX will start May with 5 x A321's and 3 x A320's this summer but only 4 x A321's showing most days in June.
