Plenty of time in lockdown, so I had a look at the BA departures for last Sunday (May 3rd) looking at seat plans an hour before departure.
There were 328 BA flights scheduled to depart, just 14 flew with passengers (some more were freight only). That's just 5% operating.
Looking at four flights seating plans, the loads were (F/J/W/Y)
ORD: 0 / 1 / 0 / 20
HKG : 5/21/10/50
JFK: 3/4/2/21
GIB: 3/58
So apart from GIB very light loads indeed (and who pays for 1st at the moment?)
The 14 destinations were:
UK: GLA, EDI
EU: LIS, BGN, AMS, TXL, CDG, GIB
WW: LAX, BOS, IAD, ORD, HKG, JFK
How long before BA matches Easyjet and stops flying entirely?
