Looks like a fun day out...
15th July A320 Mumbai-Delhi, diverts to Lucknow, further diverts to Prayagraj but ends up landing in Lucknow on vapours. All seemingly created by unforecast low vis.
From flightradar, 38 mins between entering hold pattern at DEL to missed approach and diversion. Further 10 mins holding at Lucknow before heading off to the east, then landed approx 40 mins after entering hold at Lucknow.
Nothing on AVherald
