The airframe in question appears to be 7 year old EI-ENM. These FR airframes certainly get around. It's amazing how they keep full tabs on them. How many 738s now - 444? I hope they never let it become 666
According to FR24 data for EI-ENM, (which as per usual does currently contain one or two spurious entries), this airframe is perhaps nothing less than typical in that it would appear to have flown every single day in the last 3 months bar 2 spent offline at Stansted back in April. For the 14 nights prior to the incident which occurred when it was en route to Zadar on the last sector of the day, the aircraft had been based and/or overnighted in Zadar after arriving mostly after 2300 and leaving mostly before 0700 each day. Again not unusual is that excluding the two days offline, it has averaged approx. 5 sectors per day over the last 3 months, and 7 per day whilst operating out of Zadar. On three days it seems to have done 8 sectors starting the day and ending it at Zadar including the day of the incident... I bet some airlines wished they were as busy, eh?

In the last three months, excluding a few one-off single nights at other destinations, EI-ENM seems to have been based and/or overnighted at Bratislava (6 consecutive nights), Stansted (20 nights which included the 2 days offline 23-24 April), Pafos (2 nights), Tenerife (7 nights), East Midlands (13 nights), Alicante (2 nights), Cork (2 nights), Stansted again (2 nights), Luga (7 nights), Brussels (6 nights), Zadar (14 nights) in that order (all numbers given are for consecutive nights).
