<human>: Can you give me a shortened version of the text?

My Opa (Dutch for grandfather) has cancer and is at the lowest point he's ever been. He is no longer being treated or medicated except for pain relievers. My family is expecting him to pass away very soon. I spoke to him briefly on the phone early last week and all he said was that he hoped to see me one last time before he dies. It was heartbreaking.

I'm looking to purchase a RT airline ticket online from Toronto YYZ into Schiphol Airport AMS in Amsterdam. I will hopefully be departing Wednesday or soon after, and returning back to Canada around the 23rd. I can be flexible on the return date.

My main issue is affordability vs. scheduling. There are some airlines (Air Transat) that have tickets below $600, which works with my budget, but do not depart for another couple of weeks. If someone could help me find a flight around that price or lower, and leaving as soon as possible (wednesday at the earliest), I would be forever grateful. 

Please help me see my Opa one last time before he goes :(
