Wow! Did these fees go up?
(1) I had the same issue about availability: U9 on ExpertFlyer and 4+ on UA. I booked 2 and now U0.
(2) The fees were $148 per person including a $25 phone booking fee. Various blogs were showing fees of less than $50. Seems like their fees have gone up?
(3) Question: how can I select seats on these flights? Doesn't seem to be possible on ba.com, and I can't find the reservation on aerlingus.com
