I called aeroplan this morning, here's what I got:
Jun 12, YYZ - EWR - LHR
Jun 15, LHR - LIS
----------------
Return flight on Jun 21:
Option #1: Lisbon - Milan - Toronto (AC) Tax $541
Option #2: Lisbon - London - Toronto (AC) Tax $567
Option #3: Lisbon - London - Washington - Toronto (UA) Tax $360
From all the search I've done on united.com, there's really no UA flight from LIS to YYZ with 1 transfer.
I checked airtransat.ca, YYZ - LGW, then LIS - YYZ, all direct flights $711; plus I need to buy one way ticket from LHR - LIS for $164. Total comes out to $875.
What do you guys think? Should I just buy ticket from airtransat and save my points till next time?
