Alicante
A couple of things to note on this route:
1) Vueling seem to be making it summer-only. Although it was previously showing in the booking engine as remaining 3x weekly for winter, it's now only bookable via Barcelona.
2) Although the press releases for the Ryanair S16 schedule had Alicante down to be 2x daily, the timetable is showing only 12 weekly flights in August, the busiest month, with 1 daily flight on Tuesday and Saturday. At least one of the flights on the days when this route is 2x daily should be from a BHX-based aircraft, so my guess is that the BHX-based aircraft has been reallocated (possibly for Barcelona which is 2x daily on Tuesday and Saturday). The timings are also very strange with some days seeing the two flights from ALC to BHX landing within minutes of each other.
