I booked flights from Canada to Edinburgh through Kiwi.com because the flight arrived in Edinburgh at an ideal time and it was Westjet. I noticed while booking that our cabin baggage was free however at the time of booking checked baggage was not mentioned. I assumed that would be an add on once the flight was purchased. Upon booking I realized checked baggage was not allowed however baggage insurance was available for purchase ( Im not sure why you would need insurance if your bag is with you in the cabin the whole time). Only a 7kg bag was allowed. They said it was because it's a discount rate, but by no means was this the cheapest flight. This experience has severely complicated our 10 day trip to Scotland and kiwi.com has been aggressive and reactive. It's not worth the ideal arrive time and it's not cheap.
