One of us is celiac and there are no food options on any of the flights from Montreal to Toronto to San Jose. Least co operative airline we have travelled with and just a bag of pretzels for a 5 hour flight, pretty cheap and disgusting. In future, if there are other airline options, we will choose the others.
