Can eUpgrades be used Upgrade Calgary to Vancouver on Basic Fare?
 

Trying to use altitude e upgrades credit to upgrade to q business class from calgary to vancouver
can I still do this from basic fare? Under the description it says basic fares are not eligible for upgrade. However, it is a t class and eupgrade sites states that t class tickets are eligible

thank you in advance

Have booked the Basic fares between YYC/YEG & YVR - Nope you cannot upgrade!

Basic fare is just that...BASIC.....matching Swoop and Flair air fares and the related restrictions

You could 'upfare' (on line change my booking, or by calling in) to a fare basis that allows you to use the eups. But for a short flight, it may not be worth the extra cost. The eupgrade website allows you to preview the eup/copay requirements according to the fare class/code. Before proceeding you could make a dummy booking to see if upgrade space exists (within the booking window).

Basic does not allow for upfare. (that's the rule, but I'm sure YMMV if you get an agent who doesn't know or is too lazy to read acpedia)

This'll be the opposite of a normal HUCA situation, looking for someone who doesn't know the rules. I had several flights at the end of 2018 out of several different airports (I was doing segment runs). There were several flights where I'd need to ask the Gate Agent a question prior to boarding. It seemed that each time there was someone wanting to sneak onto the flight I was on as they were at the airport early, etc. Each time the agent took the BP, or looked up the reservation they'd see Basic and politely say that they're on a Basic fare - no changes allowed. There are lots of nuances in fare rules, but I think this basic rule (no pun intended) will be widely known by agents.
