Planning an extra brief visit to EY (basically need to be there one evening/night).
Options for return flight are:
VS454 VS45
journey duration16h 30m
departure time6:55AM
arrival time4:25PM
layover airport code LHR layover duration2h 50m
arrival airport code JFK
90,500 VS + $255.07
AC81 (11:55am departure) connecting at YYZ to flight to either JFK or LGA arriving around 9pm or 10pm
135,000 - 137,300 AC + CAD100 (~ USD 74).
VS PROS: earlier arrival, lower total cost. VS CONS: departure time kills the night and doesn't allow for decent Shachris.
AC PROS: Better departure time allowing for decent night and Shachris, lower cash outlay. AC CONS: Overall higher cost, later arrival.
UNKNOWN (to me): AC J vs VS J.
Also available is IB (via BA)
81,250 Avios (62,500 AMEX with current promo) + $215.47
IB PROS: lowest cost. IB CONS: 5:30am departure, 6 hour layover in MAD, presumably fake J on TLV-MAD route.
