To clarify, the intention of this schema is for actions/transactions as
Martin suggested. An offer to sell a ticket should use schema.org/Offer. I
can update the comments to reflect this.

Martin named a number of places where the range should be extended to use
http://schema.org/QualitativeValue or
http://schema.org/QuantitativeValueas appropriate. Those seem like
good suggestions, so unless someone has
strong objections, I will update the draft to reflect those changes.

My other comments are inline.

<vth> Martin, I am not sure I completely understand this point. Without a
ticketToken (or some other way to validate the ticket), the ticket is in
effect a TicketHolder. Are you concerned that people will get confused
about the semantics of using Ticket?

<vth> The intention is to record what the person paid for the ticket in
'price'. I assume an offer price would be part of a http://schema.org/Offer.
Perhaps the price property should be changed to 'pricePaid' or similar to
clarify the difference.

http://schema.org/Thing seems very broad. Would it be better to have an
aircraft type?

<vth> Thank you for mentioning this. I knew there was some automotive stuff
