I purchased a ticket to the pre-season game last week and it was electronic only. My phone could not open the link they sent, so I got my money back. For air travel, I print my boarding passes every time. Like I say, I will never trust a phone. I also never remember to keep it charged. No problem with paper. Works every single time. There are still people who don't carry a phone, so hopefully the paper option will always be around.
