Considering the low(ish) frequencies of these new Flybe routes, and the dates on which they started, that's not too bad for a first month.
CGN - 6 weekly (May 1) - 52 flights = 32 pax per flight
LYS - 4 weekly (May 1) - 38 flights = 43 pax per flight
MXP - 5 weekly (May 1) - 44 flights = 47 pax per flight
BUD - 3 weekly (May 4) - 24 flights = 49 pax per flight
VCE - 2 weekly (May 7) - 16 flights = 38 pax per flight
PRG - 5 weekly (May 8) - 34 flights = 67 pax per flight
REU - 3 weekly (May 10) - 20 flights = 33 pax per flight
VIE - 3 weekly (May 10) - 20 flights = 71 pax per flight
DBV - 2 weekly (May 16) - 10 flights = 50 pax per flight
PGN - 2 weekly (May 25) - 4 flights = 54 pax per flight
ZAD - 2 weekly (May 27) - 4 flights = 61 pax per flight
The stats clearly show why REU and CGN were given recent discounts/promotional offers. Hopefully, as these routes become more established we will see some growth, especially leading into the summer. I don't know what the load factors are because of the aircraft alterations, and I haven't taken into consideration any cancelled/diverted flights.
