Ugh, I am trying to book a Plus fare on a 1 way Lis-Bos in late September, 2025. I go through allll the steps and then when I hit go to payment, it tells me that "it is not possible to book the flights you selected". At least it stores the passenger info to make it easier to fill in again and again. To make matters worse, somehow I want from #1 in the Chat queue to #4. Assuming I go the way of using an OTA, does anyone have experience with who does/does not offer the Plus fare? I really want the refundable benefit since my trip is so far out. Thanks,
