I haven’t been able to travel alone for a long time, either, because I can’t hear the PA system nor any instructions on board. A few years back, hubby and I booked an overseas flight 6 months in advance. We didn’t pay the extra to ensure we were placed together, because we just expected it to be a given, that far in advance . To my dismay, upon check-in, they had placed us separately - I soon figured out that this is a deliberate move, by some airlines, to induce customers to pay the pre-selection fee. Hubby was protesting that we had booked 6 months earlier, to no avail. Then I advised them of my deafness and “innocently” inquired if I should have let them know when we booked. Before we knew it, we were issued boarding passes, seated together, in PLUS class, no less. The same scenario worked for the return flight. They were lovely flights! However, the more budget airlines don’t seem to officially be very accommodating for deaf people. Other times we have had to suck it up and pay the extra. I do find that fee to be a form of passive extortion, and it should be policy to waive it for passengers with disabilities.
