I booked a few flights this year in C from EWR to LAX, all specifically on the 787-10. One of this flights (7am flight) was cancelled and they have given me the option of flights on either a 757-200 or a old-UA version of a 777 (2-4-2 layout). I don’t prefer either aircraft and the return flight is still a 787-10. If I request it, should UA cancel and fully refund the outbound per their CoC because of the flight cancellation and unavailability of any flights until 3pm that day on a 787-10 (that flight is too late to get into LA). Thank you.
